Question

Which of the following equations correctly represents the momentum p of a photon of Energy E?

A.

E / c

B.

$\text{E}^2\text c$

C.

$\text{Ec}^2$

Solution

Correct option is A

$\text{The energy } E \text{ of a photon and its momentum } p \text{ are related by the equation:}\\E = pc \implies p = \frac{E}{c}$
