Dual Nature Of Light Question 231
Question: The frequency of a photon, having energy 100 $ eV $ is $ (h=6.6,{{10}^{-34}},J\text{-}sec) $ [AFMC 2000]
Options:
A) $ 2.42\times 10^{26}Hz $
B) $ 2.42\times 10^{16}Hz $
C) $ 2.42\times 10^{12}Hz $
D) $ 2.42\times 10^{9}Hz $
Show Answer
Answer:
Correct Answer: B
Solution:
$ E=h\nu \Rightarrow 100\times 1.6\times {{10}^{-19}}=6.6\times {{10}^{-34}}\times \nu $
$ \Rightarrow \nu =2.42\times 10^{16}Hz $ .
