Dual Nature Of Light Question 150
Question: Photon and electron are given same energy $ ({{10}^{-20}}J) $ . Wavelength associated with photon and electron are $ {\lambda_{Ph}} $ and $ {\lambda_{el}} $ then correct statement will be [RPMT 2001]
Options:
A) $ {\lambda_{Ph}}>{\lambda_{el}} $
B) $ {\lambda_{Ph}}<{\lambda_{el}} $
C) $ {\lambda_{Ph}}={\lambda_{el}} $
D) $ \frac{{\lambda_{el}}}{{\lambda_{Ph}}}=C $
Show Answer
Answer:
Correct Answer: A
Solution:
Wavelength of photon will be greater than that of electron because mass of photon is less than that of electron
$ \Rightarrow {\lambda_{ph}}>{\lambda_{e}} $
