Wavelength and Wavenumber
« on: February 03, 2005, 03:00:52 PM »
What are the similarities between wavelength and wavenumber? I cannot think of any, except that they involve waves. Their definitions are:

Wavelength: distance between two peaks or troughs of a wave
Wavenumber: number of wavelengths that fit into 1 cm.

Wavelength is a measure of the actual size of the wave.  It has units of length.

Wavenumber is a measure of energy in the wave.  The units cm-1 are really units of energy, like Joules of calories.

They are for the most part, just different ways of measuring the same thing.
