Given below are two statements: one is labelled as Assertion 
and the other is labelled as Reason 
.
Assertion A: Number of photons increases with increase in frequency of light.
Reason R: Maximum kinetic energy of emitted electrons increases with the frequency of incident radiation.
In the light of the above statements, choose the most appropriate answer from the options given below:
and 
are correct and 
is the correct explanation of 
. 
and 
are correct and 
is NOT the correct explanation of 
. 
is not correct but 
is correct. 
is correct but 
is not correct.
Text Solution
Verified by ExpertsC
Intensity of light 
Here 
is no. of photons per unit time.
so on increasing frequency 
decreases taking intensity constant.
So on increasing 
, kinetic energy increases.
