Photons: Energy, Momentum & Radiation Pressure question from NEET 1993 (AIPMT)

Q45NEET 1993 · AIPMTEasy

Photons: Energy, Momentum & Radiation Pressure

Momentum of photon wavelength λ\lambda is

Show answer and solution

Answer: (a)

  1. Photon momentum p=hλp = \frac{h}{\lambda}.
  2. With λ=cν\lambda = \frac{c}{\nu}: p=hνcp = \frac{h\nu}{c}.
  3. So the answer is (a) hνc\frac{h\nu}{c}.
