If you know the frequency of the photon, you can calculate the wavelength using the equation $λ = \frac{c}{ν}$ $lambda=c/nu$ where $c$ $c$ is the speed of light and $ν$ $nu$ is the frequency.

Example: for a photon of frequency $6 \times 10^{12} s^{- 1}$ $6times10^(12) s^(-1)$ the wavelength is

$λ = \frac{3 \times 10^{8} \frac{m}{s}}{6 \times 10^{12} s^{- 1}} = 5 \times 10^{- 5} m = 50 m i c r o m e t e r s$ $lambda=(3times10^8 m/s)/(6times10^(12) s^(-1))=5times10^(-5) m=50 micrometers$
