I read the FAQ about photons not having mass: https://www.physicsforums.com/threads/do-photons-have-mass.511175/

But De-Broglie's equation says that wavelength=Plank constant / mass x velocity

i.e.

λ=h/mv

inserting values in the above relation we find the mass of a photon having certain wavelength
