Answer:
Explanation:
When the intensity of light is increased, it causes a large number of electrons to be ejected from the surface of metal. since photoelectric current is directly proportional to the number of photoelectrons emitted per second. ... the maximum K.E of electrons is independent of the intensity of the light
