Question -
Answer -
The momentum of a photon having energy (hν)is given as:
Where,
λ = Wavelength of theelectromagnetic radiation
c = Speed of light
h = Planck’s constant
De Broglie wavelength ofthe photon is given as:
Where,
m = Mass of the photon
v = Velocity of the photon
Hence,it can be inferred from equations (i) and (ii) that thewavelength of the electromagnetic radiation is equal to the de Brogliewavelength of the photon.
