Question

The kinetic energy of the photoelectron depends upon the:- (1) Intensity of striking light (2) Number of photons striking (3) Frequency of striking light (4) Number of photo electrons ejected.

Answer 1

Answer:

It depends on the frequency of striking[incident] light.

Explanation:

it is independent of its intensity.                                                                                                              K.E ∝ ν  [frequency of incident light]                                                                                                                                           1/2mv^2 ∝ ν
