Answer:
no effect
Explanation:
When a suitable frequency of light falls on a metal surface the photo electrons are ejected from the metal surface. This phenomenon is called photo electric effect.
As the frequency of the incident light increases, the maximum kinetic energy of the photo electrons increases.
As the intensity of incident light increases, the number of photo electrons emitted increases, so that the photo electric current increases.
There is no effect of the frequency of incident light on the number of photo electrons.
