WebDerivation. de Broglie derived the above relationship as follows: 1) E = hν for a photon and λν = c for an electromagnetic wave. 2) E = mc 2, means λ = h/mc, which is equivalent to λ = h/p. Note: m is the relativistic mass, and not the rest mass; since the rest mass of a photon is zero. Now, if a particle is moving with a velocity v, the ...
