Why Is the Sky Blue? | Physics for Kids

Images sent back from the Viking Mars landers in 1977 and from Pathfinder in 1997showed a red sky seen from the Martian surface. This was due to red iron-rich duststhrown up in the dust storms occurring from time to time on Mars. The colour of theMartian sky will change according to weather conditions. It should be blue when therehave been no recent storms, but it will be darker than the earth’s daytime sky because ofMars’ thinner atmosphere.

Why Is The Sky Blue What’s You Answer

He moved to Switzerland to go to college at the Federal Polytechnic School to teach Physics and Math. Also near rivers, lakes and oceans the moisture is very high because when the water becomes warm from the sun, it evaporates into the sky. This is because Climate Change has got nothing to do with the Blue color of the sky. So by moving charges back and forth, thisx will produce electric and magnetic fields that can travel at the speed of light. Light from the sun has colors which in most of the time cannot be seen.

Right Now Were Talking Rayleigh Scattering

Our atmosphere is made up of tiny molecules, mostly oxygen and nitrogen. When the beams of light enter the atmosphere, they collide with these molecules and scatter this is called Rayleigh Scattering. These light rays then scatter at varying rates depending on the size of the wavelength, with larger wavelengths scattering much less. Basically, blue light rays will scatter much more than red ones, which is why more blue-coloured light rays end up in our vision when we look at the sky. As the light rays scatter, they lose their intensity, which explains how more red and green beams sneak into the mix and sometimes add a reddish-orange tinge to the sky.

It’s Easy To See That The Sky Is Blue Have You Ever Wondered Why

A lot of other smart people have, too. And it took a long time to figure it out!

The light from the Sun looks white. But it is really made up of all the colors of the rainbow.

When white light shines through a prism, the light is separated into all its colors. A prism is a specially shaped crystal.

If you visited The Land of the Magic Windows, you learned that the light you see is just one tiny bit of all the kinds of light energy beaming around the universe–and around you!

Like energy passing through the ocean, light energy travels in waves, too. Some light travels in short, “choppy” waves. Other light travels in long, lazy waves. Blue light waves are shorter than red light waves.

All light travels in a straight line unless something gets in the way and does one of these things:

Sunlight reaches Earth’s atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered in all directions by the tiny molecules of air in Earth’s atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.

Closer to the horizon, the sky fades to a lighter blue or white. The sunlight reaching us from low in the sky has passed through even more air than the sunlight reaching us from overhead. As the sunlight has passed through all this air, the air molecules have scattered and rescattered the blue light many times in many directions.

Why is the sky blue?

It all depends on whats in the atmosphere! For example, Mars has a very thin atmosphere made mostly of carbon dioxide and filled with fine dust particles. These fine particles scatter light differently than the gases and particles in Earths atmosphere.

Why is the sky blue? Light at the violet end of the spectrum travels in shorter, tighter waves, which are affected more by the molecules in the atmosphere than the longer, lower-frequency waves at the red end. It indicates that the cloud has enough moisture to absorb all the light passing through them from above or that sunlight is blocked by the sun setting over the horizon.

The Special Theory of Relativity by Albert Einstein The Special Theory of relativity is an acknowledged physical theory that revolutionized advancements in the relationship between space, and time.

How Is Light Scattered

The Earths atmosphere is composed of lots of different air molecules. Sunlight can be redirected by the air molecules and this is known as ‘scattering’.

The size of these molecules is much smaller than the wavelengths of visible light. The type of scattering that occurs is known as Rayleigh scattering named after Lord Rayleigh who discovered it.

This type of scattering increases as the wavelength of light decreases, so blue light is scattered more than red light by the tiny air molecules in our atmosphere.

Why Is The Sky Blue?

As the Sun gets lower in the sky, its light passes through more of the atmosphere to reach you. Even more of the blue and violet light is scattered, allowing the reds and yellows to pass straight through to your eyes without all that competition from the blues.

Also, larger particles of dust, pollution, and water vapor in the atmosphere reflect and scatter more of the reds and yellows, sometimes making the whole western sky glow red.

Another thing I would like to mention is science. There is no reason for certain things to be the way they are, but we accept them to be the only way of life and even fight over it. Aside from blue and white, the sky featured in this panel also has patches of orange and red â a sign of the upcoming sunrise or sunset. The most common reason some clouds appear pink is simply due to something called atmospheric optics. This is know as the Tyndall Effect, frequently recognized to physicists as Rayleigh scatteringâafter Lord Rayleigh, who analyzed it in greater detail a couple of years later.

The Sky During The Day

Why Is The Sky Blue

At noon, when the Sun is overhead it appears white. This is because the light travels a shorter distance through the atmosphere to get to us its scattered very little, even the blue light.

During the day the sky looks blue because its the blue light that gets scattered the most. Its redirected into many different directions all over the sky, whereas the other wavelengths arent scattered as much.

In reality, violet light has a shorter wavelength compared to blue light and therefore its scattered more so why isnt the sky violet?

Its because our eyes are actually more sensitive to detecting blue light, and more of the sunlight coming into the Earths atmosphere is blue rather than violet.

Why Is The Sky *uniformly* Blue

I’ve read a lot of answers to the questions why the sky is blue. However all the answers I found contain mostly qualitative analysis: Rayleigh scattering is changing the direction of blue light, so there is more blue light coming to the eye along the line of sight than the red one.

However these explanations raise additional questions.

First of all, the scheme of only single scattering seems to be an oversimplification: the light direction should be changed more than once. Can we prove that this is negligible by calculation, or is it not negligible? Does this change the analysis?

Further, the explanation says nothing about the exact amount of the blue light being scattered when looking into a particular direction. Assuming the sun is in zenith, it follows from symmetry that the color of the sky in the directions having the same zenith angle must be the same, but closer to the horizon the way of the scattered light differs a lot from the rays coming near zenith so is it possible to derive theoretically a formula which would predict the color of sky given the azimuth angle and the position of the Sun ? It’s not clear why the color should not rapidly change from near blue at horizon to almost red near the Sun position: after all, the atmosphere is thicker along the lines going closer to horizon! The sky seems to be more uniformly blue than the typical explanation suggests.

I’m mainly interested in quantitative analysis, not the observations or qualitative considerations.

Its A Question That Only Leads To More Questions

Why is the sky blue?


This is actually a question that Roger Rassool, an associate professor in particle physics at the University of Melbourne, answered way back in 2013. This was his answer then:

Why is the sky blue? It is a question that, in true Sumner Miller fashion, leads to many more: What is light? What is the sky made of? How do we perceive colour?

To answer those questions we first turn to Isaac Newton who once said, If I have seen further than others, it is by standing on the shoulders of giants. Like everyone else in the 17th century, Newton marvelled at seeing a beam of sunlight enter a polished glass prism and emerge as a rainbow of colours. Some thought the prism itself contained the rainbow and the light beam was pushing it out. Newton had another suspicion. He directed the spreading rainbow of rays on to a second prism. What emerged at the far end was a restored beam of white light. Newton showed the prism was not concealing a rainbow it was splitting light into its component colours.

So Newton takes us the first step of the way by showing that sunlight is made up of the colours of the rainbow.

This was when he climbed on to Newtons shoulders to take his findings further. Newton had shown that light was made of different colours Young had shown that it was a wave. So perhaps the different colours were in fact light with different wavelengths. Bingo! Young takes us a second step on the way.

Why Is The Sky Blue

Here’s the short answer…

As white light passes through our atmosphere, tiny air molecules cause it to scatter.

The scattering caused by these tiny air molecules increases as the wavelength of light decreases.

Violet and blue light have the shortest wavelengths and red light has the longest.

Therefore, blue light is scattered more than red light and the sky appears blue during the day.

When the Sun is low in the sky during sunrise and sunset, the light has to travel further through the Earths atmosphere.

We dont see the blue light because it gets scattered away, but the red light isnt scattered very much so the sky appears red.

Why Is The Sky Blue Or Better Yet Why Is The Ocean Blue

Why is the Sky Blue? | Scattering of Light

The sky is blue due to a phenomenon called Raleigh scattering. This scattering refers to the scattering of electromagnetic radiation by particles of a much smaller wavelength. Sunlight is scattered by the particles of the atmosphere, and what comes through down to earth is called diffuse sky radiation, and though only about 1/3rd of light is scattered, the smallest wavelengths of light tend to scatter easier. These shorter wavelengths correspond to blue hues, hence why when we look at the sky, we see it as blue. At sunset and sunrise, the angle at which sunlight enters the atmosphere is significantly changed, and most of the blue and green wavelengths of light are scattered even before reaching the lower atmosphere, so we see more of the orange and red colours in the sky.

Why The Sky Is Blue

A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. Frost specifically speaks of recognizing the abundance everyone has of the color blue. . Rayleigh scattering is also the reason why the setting Sun appears red: the blue light has been scattered away from the direct sunlight. Light travels in the form of wave and different colours have a different wavelength. The men work hard to keep the community clean.

Clear skies above the Royal Observatory in Greenwich make for a fantastic view but why is the sky blue?

Its a common misconception that the sky is blue because it reflects the blue of the seas and oceans.

In fact, its the Earths atmosphere, and a process known as ‘scattering’, that causes our skies to be blue.

Why Does Scattering Matter

Why Is The Sky Blue? Simple Science (Video) (With images)

How much of the Suns light gets bounced around in Earths atmosphere and how much gets reflected back into space? How much light gets soaked up by land and water, asphalt freeways and sunburned surfers? How much light do water and clouds reflect back into space? And why do we care?

Sunlight carries the energy that heats Earth and powers all life on Earth. Our climate is affected by how sunlight is scattered, reflected back to space, or absorbed by forests, deserts, snow- and ice-covered surfaces, different types of clouds, smoke from forest fires, and other pollutants in the air.

Just as Earth’s atmosphere bends and scatters light that passes through it from the Sun to the surface, the atmosphere affects light reflecting off the surface back into space.

That is why satellites can perform what is called remote sensing from space and reveal a great deal about the surface and about the atmosphere. Instruments on satellites such as the GOES, pictured above, can measure the intensity of light of different wavelengths. Analyzing that information, atmospheric scientists find out surface and atmospheric temperatures, levels of carbon dioxide, water vapor, pollutants, ozone, and other trace gases.

GOES takes good advantage of our atmosphere’s affect on light to help us forecast the weather and understand and take care of our planet.

Moving Onto The Power Of The Sun

The sun is rapid-firing parallel rays of white light towards the Earth, which is made up of all the wavelengths of the visible spectrum at equal intensity. The colours themselves vary in wavelength, from 750 nanometres on the warmer end of the spectrum, to 450 nanometres on the cooler side. These concentrated beams of light penetrate through the Earths atmosphere and bounce off various molecules.

Why Does The Sky Look Red During Sunrise And Sunset

During sunrise or sunset, the sky appears to change colour.

When the Sun is low in the sky, the light has to travel a longer distance through the Earths atmosphere so we dont see the blue light because it gets scattered away.

Instead we see the red and orange light that travels towards us since this light hasnt been scattered very much. Hence the Sun and skies look redder at dawn and dusk.
