Ev wavenumber
Webwavenumber, also called wave number, a unit of frequency, often used in atomic, molecular, and nuclear spectroscopy, equal to the true frequency divided by the speed of the wave and thus equal to the number of waves in a unit distance. In the case of light, the frequency, symbolized by the Greek letter nu (ν), of any wave equals the speed of light, … WebThis means you can calculate the wavenumber with a frequency and a speed, noting that for light waves, the speed is always v = c = 2.998 × 10 8 meters per second. Choose the Right Form of the Equation Use the following relationship to calculate the spatial wavenumber (represented here by ν, although other symbols are sometimes used): ν = …
