Photons: Energy, Momentum & Radiation Pressure

If a photon has velocity $c$ and frequency $\nu$ , then which of the following represents its wavelength?

Show answer and solution

Answer: (c)

$\lambda = \frac{c}{\nu}$ and $E = h\nu \Rightarrow \nu = \frac{E}{h}$ .
$\lambda = \frac{hc}{E}$
So the answer is (c).
