Question

The kinetic energy of photon electron depends on 
A) Frequency of incident radiation 
B) Velocity of incident radiation
C) Intensity of incident radiation
D) Wavelength of incident radiation


A
Both A and B
loader
B
Both A and D
loader
C
Both B and C
loader
D
Both C and D
loader

Solution

The correct option is A Both A and D
$$hv = hv_{0} + KE $$ 
Kinetic energy of the photon electrons emitted depends on the frequency of incident light. More is frequency of incident light, more is the K.E. of emitted electron and therefore more is the velocity of emitted electrons.
