Explanation:

As (wavelength)=h/mv; if the wavelength is equal then, the momentum (mv) is equal.
=> photon`s rest mass = 0.
However, from the theory of relativity, it has momentum. Hence, neither the velocity nor the mass of photon can be equal to electron as photon has a zero rest mass but the momentum is equal as the wavelength is.
