Question:

The distribution function \( f(E) \) for a photon gas is given by:

Show Hint

Photons obey Bose-Einstein distribution because they are bosons with zero chemical potential.

  • \( e^{-E / k_B T} \)
  • \( \frac{E}{k_B T} e^{-E / k_B T} \)
  • \( \frac{1}{e^{E / k_B T} - 1} \)
  • \( \frac{1}{e^{-E / k_B T} + 1} \)

The Correct Option is C

Solution and Explanation

Photon gas follows Bose-Einstein statistics. The occupation number distribution for bosons (such as photons) is given by:
\[ f(E) = \frac{1}{e^{E / k_B T} - 1} \]
