The frequency of the incident light falling on a photosensitive metal plate is doubled, the kinetic energy of the emitted photoelectrons is
Text Solution
Verified by ExpertsThe correct answer is:
C
Let 
and 
be the KE of photoelectrons for incident light of frequency 
and 
respectively.
Then 
and 
So, 
or 
It means the KE of photoelectron becomes more than double
