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
