Question

Which is the incorrect statement regarding photoelectric effect ? a) Photoelectric effect will cause only when incident radiation energy more than work function b) The number of electron produces can be increased with the intensity of light c) The Kinetic energy of electron produces can be increased with the intensity of light

Answer 1

Answer:

C

Explanation:

According to laws of photoelectric emission ,The kinetic energy of a photoelectrones depends only on frequency of incident light and is independant on intensity of light

When intensity of incident radiation increases photocurrent that is, the number of electrones produced by the incident light.
