Dual Nature Of Light Question 228
Question: Frequency of photon having energy 66 eV is [CPMT PMT 1997]
Options:
A) $ 8\times {{10}^{-15}}Hz $
B) $ 12\times {{10}^{-15}}Hz $
C) $ 16\times 10^{15}Hz $
D) None of these
Show Answer
Answer:
Correct Answer: C
Solution:
$ E=h\nu \Rightarrow \nu =\frac{E}{h}=\frac{66\times 1.6\times {{10}^{-19}}}{6.6\times {{10}^{-34}}} $ $ =16\times 10^{15}Hz $
