If you know the frequency of the photon, you can calculate the wavelength using the equation #lambda=c/nu# where #c# is the speed of light and #nu# is the frequency.

Example: for a photon of frequency #6times10^(12) s^(-1)# the wavelength is

#lambda=(3times10^8 m/s)/(6times10^(12) s^(-1))=5times10^(-5) m=50 micrometers#
