Dual Nature Of Light Question 318
Question: Light of frequency 4n0 is incident on the metal of the threshold frequency n0. The maximum kinetic energy of the emitted photoelectrons is [MP PET 2002]
Options:
A) $ 3,h{\nu_{0}} $
B) $ 2,h{\nu_{0}} $
C) $ \frac{3}{2},h{\nu_{0}} $
D) $ \frac{1}{2}h{\nu_{0}} $
Show Answer
Answer:
Correct Answer: A
Solution:
$ E=h{\nu_{0}}+{K_{\max }}\Rightarrow h(4{\nu_{0}})=h{\nu_{0}}+{K_{\max }} $
$ \Rightarrow {K_{\max }}=3,h{\nu_{0}} $ .
