If h is the Planck's constant, then the momentum of the photon having frequency $v$ is represented by
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → $hv/c$
Energy of a photon: $E = h \nu$
Relativistic relation between energy and momentum for a photon: $E = pc$
So, momentum: $p = \frac{E}{c} = \frac{h \nu}{c}$
Final Answer: $p = \frac{h \nu}{c}$
