Q164 / 170 · Manipal (MET) 2016 · Physics

In photoelectric effect, the photo current

A
increases with increase of frequency of incident photon
B
decreases with increase of frequency of incident photon
Correct answer
C
does not depend on the frequency of photon but depends only on intensity of is cident light
D
depends both on intensit, and frequency of incident beam

Solution

When intensity of incident photon increases number of electrons emitted from the surface increases. Thus current increases. It is independent of frequency of photon.

Hence, the correct answer is option: 'C'.
