As ^(wavelength)=h/mv if the wavelength is equal then the momentum(mv) is equal ( as h= plank`s constant).photon`s rest mass is 0. But from the theory of relativity we come to know that it has momentum. So neither the velocity nor the mass of photon can be equal to electron as photon has a 0 rest mass but the momentum is equal as the wavelength is.With regards..
