Question

The momentum of photon whose frequency f is
(a) hf/c
(b) hc/f
(c) h/f
(d) c/hf

Answer 1

Answer:Gamma rays

Gamma rays, a form of nuclear and cosmic EM radiation, can have the highest frequencies and, hence, the highest photon energies in the EM spectrum. For example, a γ-ray photon with f = 1021 Hz has an energy E = hf = 6.63 × 10−13 J = 4.14 MeV.
