Answer
The cut off frequency does not depend on the intensity of incident light.
Work Step by Step
-Intensity of light is a measure of the number of photons striking unit surface area.
-Cut-off frequency is the minimum frequency that the incident ray should have for electrons to be ejected out of a surface.
Since intensity is a measure of the NUMBER of electrons and cut-off frequency is a measure of the ENERGY of electrons, the. two are not related to each other.
