Photons: Energy, Momentum & Radiation Pressure

Photon of frequency ν\nu has a momentum associated with it. If cc is the velocity of light, the momentum is

Show answer and solution

Answer: (a)

  1. E=hνE = h\nu and for a photon p=Ecp = \frac{E}{c}.
  2. p=hνcp = \frac{h\nu}{c}
  3. So the answer is (a) hν/ch\nu/c.
