The magnetic field associated with a light wave is given at the origin by 
If this light falls on a silver plate having a work function of 
, what will be the maximum kinetic energy of the photoelectrons? 
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
(According to question, there are two 
waves with different frequency,)
and 
To get maximum kinetic energy we take the photon with higher frequency
Using, 
where 
is speed of light 
Clearly, 
so 
of photoelectron will be maximum for photon of higher energy.
energy of photon
