There are n₁ photons of frequency ${\gamma }_1$ in a beam of light. In an equally energetic beam, there are n₂ photons of frequency ${\gamma }_2$.Then the correct relation is

• A

  $\frac{n_1}{n_2}=1$

• B

  $\frac{n_1}{n_2}=\frac{{\gamma }_1}{{\gamma }_2}$

• C

  $\frac{n_1}{n_2}=\frac{{\gamma }_2}{{\gamma }_1}$

• D

  $\frac{n_1}{n_2}=\frac{{\gamma }_1^2}{{\gamma }_2^2}$
