Suppose that for a particular metal, the photoelectric effect occurs with light

Question

Suppose that for a particular metal, the photoelectric effect occurs with light of wavelength ?0. With this light incident on a small region of metal, measurements show that electrons leaving the surface have kinetic energies as large as E0. If the intensity of light is increased without changing the wavelength, (a) how does this affect the number of electrons leaving the surface? (b) What is the effect on the maximum kinetic energy of the ejected electrons?

(a)
There are fewer electrons leaving the surface.
The number of electrons leaving the surface is unchanged.
There are more electrons leaving the surface.

(b)
The electrons' maximum kinetic energy is less than E0.
The electrons' maximum kinetic energy is still equal to E0.
The electrons' maximum kinetic energy is greater than E0.

Explanation / Answer

a) There are more electrons leaving the surface. b) The electrons' maximum kinetic energy is still equal to E0.
