Photons: Energy, Momentum & Radiation Pressure

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

Show answer and solution

Answer: (c)

  1. λ=cν\lambda = \frac{c}{\nu} and E=hν⇒ν=EhE = h\nu \Rightarrow \nu = \frac{E}{h}.
  2. λ=hcE\lambda = \frac{hc}{E}
  3. So the answer is (c).
