Dual Nature Of Light Question 235
Question: There are $ n_{1} $ photons of frequency $ {\gamma_{1}} $ in a beam of light. In an equally energetic beam, there are $ n_{2} $ photons of frequency $ {\gamma_{2}} $ . Then the correct relation is [KCET 2003]
Options:
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}} $
Show Answer
Answer:
Correct Answer: C
Solution:
$ E=nh\nu \Rightarrow \nu \propto \frac{1}{n}\Rightarrow \frac{n_{1}}{n_{2}}=\frac{{\gamma_{2}}}{{\gamma_{1}}} $ .
