Wavelength can be calculated using the following formula: wavelength = wave velocity/frequency. Wavelength usually is expressed in units of meters. Wavelength () is the distance over which the shape of a wave repeats. A wavelength of energy that is also called a reciprocal centimeter. Wavelength is the distance between two peaks (or troughs) of a wave, and is therefore measured in meters. The distance between two peaks (above the surface) is the wavelength of the transverse wave. To calculate the wavenumber and frequency of yellow radiation (wavelength, = 5800 10 m), follow the given instructions: Using the wavenumber formula, wavenumber = 1 / wavelength, determine the wavenumber as: wavenumber = 1/ (5800 10 m) = 1.724 10 m.
