A laser emits a beam of light whose photons all have the same frequency. When the beam

Question:

A laser emits a beam of light whose photons all have the same frequency. When the beam strikes the surface of a metal, photoelectrons are ejected from the surface. What happens if the laser emits twice the number of photons per second?

(a) The photoelectrons are ejected from the surface with twice the maximum kinetic energy.

(b) The photoelectrons are ejected from the surface with the same maximum kinetic energy.

(d) Both b and c happen.

(e) Both a and c happen.
