Dual Nature Of Light Question 226
Question: What is the momentum of a photon having frequency $ 1.5\times 10^{13}Hz $ [BHU 1997]
Options:
A) $ 3.3\times {{10}^{-29}}kg\ m/s $
B) $ 3.3\times {{10}^{-34}}kg\ m/s $
C) $ 6.6\times {{10}^{-34}}kg\ m/s $
D) $ 6.6\times {{10}^{-30}}kg\ m/s $
Show Answer
Answer:
Correct Answer: A
Solution:
$ p=\frac{h\nu }{c}=\frac{6.6\times {{10}^{-34}}\times 1.5\times 10^{13}}{3\times 10^{8}} $ $ =3.3\times {{10}^{-29}}kg\text{-}m/\sec $
