This chemistry video tutorial explains how to solve problems involving the speed of light, wavelength, and frequency of a photon. It is the distance between consecutive corresponding points of the same phase on the wave, such as two adjacent crests, troughs, or zero crossings, and is a characteristic of both traveling waves and standing waves, as well as other spatial wave patterns. How to calculate wavelength? Start studying Chemistry Chapter 5- Light, Energy, and Wavelength. He holds bachelor's degrees in both physics and mathematics. The wavelengths of visible light extend from about 700 nm (red) to 400 nm (violet). Telecommunication Dictionaries. Dispersion is defined as the spreading of white light into its full spectrum of wavelengths.
