Show that the wavelength of electromagnetic radiation is equal to the de Broglie wavelength of its quantum (photon).
We know momentum of photon, p=λh ⇒λ=ph −(1) De broglie wavelength of photon, λ=mvh Also, p=mv ∴λ=ph −(2) From (1) and (2), it can be inferred that wavelength of electromagnetic and de-Broglie are same.
