Difference between wave number and frequency in radiation​

Answer»

Frequency is a MEASUREMENT of the number ofwave CYCLES per second. Wavenumber is the reciprocal of the wavelength MULTIPLIED by a constant. Although they look the same, thedifference is that wavenumber has NOTHING to do with the velocity of the wave- wavenumber is measured in cm^-1, which doesn't include a time unit.
