In an experiment, light of a particular wavelength is incident on a metal surface, and electrons are emitted from the surface as a result. To produce more electrons per unit time but with less kinetic energy per electron, the experimenter should do which of the following? Select two answers:

a. Increase the intensity and decrease the wavelength of the light.
b. Increase the intensity and the wavelength of the light.
c. Decrease the intensity and the wavelength of the light.
d. Decrease the intensity and increase the wavelength of the light.
e. None of the above would produce the desired result.
