When light is incident on a metal surface, it emits electrons. what happens if the intensity of light increases?

a. the intensity of light has no effect on the electrons.

b. the rate of electrons emitted decreases.

c. the rate of electrons emitted increases.

d. the energy of the electrons emitted increases.

e. the energy of the electrons emitted decreases.

The correct answer is "The energy of the electrons emitted increases".

Explanation:

Photoelectric effect: It is the phenomenon in which the light of the particular frequency incidents on the surface of the metal then there is an emission of the electrons.

In this phenomenon, the saturation current increases with the increase in the intensity of the light.

The rate of flow of electrons constitutes the current. If the intensity of light increases then the rate of the electrons also increases.

In the given problem, When light is incident on a metal surface, it emits electrons. The rate of the electrons emitted increases.

Therefore, the correct option is (C).

FOR PLATO, the answer is

C. The rate of electrons emitted increases

Explanation:

The rate of flow of electrons constitutes the current. If the intensity of light increases then the rate of the electrons also increases.
