A metal surface is illuminated with blue light and electrons are ejected at a given rate each with a certain amount of energy. If the intensity of the blue light is increased, electrons are ejected
A)at the same rate, but with more energy per electron.
B)at the same rate, but with less energy per electron.
C)at an increased rate with no change in energy per electron.
D)at a reduced rate with no change in energy per electron.

Question

Quizplus · Accepted Answer

Increasing the intensity of light increases the number of photons, thus increasing the rate of electron ejection, but the energy per electron depends on the frequency of the light, which remains unchanged.
