Photon of frequency v\mathrm{v} has a momentum associated with it. If c\mathrm{c} is the velocity of light, the momentum is

Options

  1. Av/c\mathrm{v / c}
  2. Bhvc\mathrm{hvc}
  3. Chv/c2\mathrm{h v / c^2}
  4. Dhv/c\mathrm{hv/c}

Correct answer

D. hv/c\mathrm{hv/c}

Step-by-step solution

P=hλ=hvc\mathrm{P}=\frac{\mathrm{h}}{\lambda}=\frac{\mathrm{h} v}{\mathrm{c}}
