A laser emits a beam of light having photons all having similar frequency. If the beam hits the surface of a metal, photoelectrons are ejected from the surface. What occurs when the laser emits two times the number of photons per second?
(i) The photoelectrons are emitted from the surface having twice the maximum kinetic energy.
(ii) The photoelectrons are emitted from the surface having the similar maximum kinetic energy.
(iii) The number of photoelectrons emitted per second from the surface doubles.
(iv) Both b and c occur.
(v) Both a and c occur.
