Photo electric effect is the phenomenon in which

A

Photons come out of a metal when it is hit by a beam of electrons

B

Photons come out of the nucleus of an atom under the action of an electric field

C

Electrons come out of metal with a constant velocity depending on frequency and intensity of incident light

D

Electrons come out of a metal with different velocity not greater than a certain value which depends only on the frequnecy of the incident light wave and not on its intersity.

Text Solution

Verified by Experts

The correct Answer is:
D

In photo electric effect the maximum velocity of `e^(-)` will corresoponding to `KE_("max")` & other are less than it.
