Dual Nature Of Light Question 213
Question: The momentum of the photon of wavelength 5000Å will be [CPMT 1987]
Options:
A) $ 1.3\times {{10}^{-27}}kg\text{-} $ m/sec
B) $ 1.3\times {{10}^{-28}}kg\text{-} $ m/sec
C) $ 4\times 10^{29}kg\text{-} $ m/sec
D) $ 4\times {{10}^{-18}}kg\text{-} $ m/sec
Show Answer
Answer:
Correct Answer: A
Solution:
$ p=\frac{h}{\lambda } $ $ =\frac{6.6\times {{10}^{-34}}}{(5000\times {{10}^{-10}})}=1.3\times {{10}^{-27}}kg\text{-}m/s $
