Sample Problem: Wavelength And Frequency

The color orange within the visible light spectrum has a wavelength of about 620 nm. What is the frequency of orange light?

Step 1: List the known quantities and plan the problem.


  • speed of light = 3.00 × 108 m/s
  • conversion factor 1 m = 109 nm


  • Frequency

Convert the wavelength to m, then apply the equation c = and solve for frequency. Dividing both sides of the equation by yields:


Step 2: Calculate



Step 3: Think about your result.

The value for the frequency falls within the range for visible light.

    Nu Symbol In Greek Alphabet

    Nu is the 13th letter of the Greek alphabet. And it has the value of 50 in the Greek number system. The letter came from the Phoenician language nun , which was used to mean serpent. The uppercase Nu is exactly like the Latin N. So that’s why it isn’t used now. On the other hand, the minuscule nu is used in many areas like statistics, thermodynamics, physics, material science and chemistry.

    The lower-case letter Nu “” is used in the Modal -calculus in theoretical computer science. The letter also denotes the degree of freedom in statistics, neutrino, kinematic viscosity, and the frequency of a wave in physics, as well as the specific volume of a substance in thermodynamics. In biology, the lowercase letter Nu stands for Polymerase nu. In chemistry, the letter is used as a symbol for the stoichiometric coefficient. In addition, is used to represent Poisson’s ratio that is a measure of the Poisson effect and named after the French mathematician, engineer, and physicist Siméon Denis Poisson.

    Why Is V Used For Frequency

    Specifically, frequency times wavelength equals speed. Wave speed is also sometimes called velocity. The relationship between frequency, wavelength, and velocity is expressed mathematically as f ·? = v. In this equation, f is frequency ? is lambda, the Greek letter used to symbolize wavelength and v is velocity.

    Nu Medica Webinar on Functional Blood Chemistry

    While many of the Nu Skin products are formulated well, we understand this brand isnt for everyone. Whether the products dont react well with your skin or the products are simply out of reach due to the high cost, we have a couple alternatives for you to consider.

    One brand we recommend is Formulyst because, unlike most skin care brands, Formulyst maximizes the use of powerful ingredients and minimizes the use of superficial ones. The result is clinically advanced skincare solutions that help to promote healthy, more youthful-looking skin.

    For hydrated and dewy looking skin, try Formulyst Super Hyaluronic Water Moisturizer. Hyaluronic acid helps keep skin plumped, hydrated, and dewy looking. This oil free formula is packed with multiple types of hyaluronic acid and it works as a moisture magnet by drawing water to the skin.

    Another brand that balances the power of plants with cutting edge science is Carrot & Stick. Not only is Carrot & Stick good for your skin, it is also good for the environment as the formulas skip harmful chemicals commonly found in skin care products.

    Melting And Boiling Properties

    Organic compounds typically melt and many boil. In contrast, while inorganic materials generally can be melted, many do not boil, and instead tend to degrade. In earlier times, the melting point and boiling point provided crucial information on the purity and identity of organic compounds. The melting and boiling points correlate with the polarity of the molecules and their molecular weight. Some organic compounds, especially symmetrical ones, sublime. A well-known example of a sublimable organic compound is para-dichlorobenzene, the odiferous constituent of modern mothballs. Organic compounds are usually not very stable at temperatures above 300 °C, although some exceptions exist.
