Question

When light falls on a metal surface, the maximum kinetic energy of the emitted photoelectrons depends upon ______

Options

• the time for which light falls on the metal.

• frequency of the incident light.

• the intensity of the incident light.

• the velocity of the incident light.

Answer 1

When light falls on a metal surface, the maximum kinetic energy of the emitted photoelectrons depends upon the frequency of the incident light.

Explanation:

K.E._max = h(v - v₀); v = frequency of incident light.
