Photoelectric effect: Monochromatic light strikes a metal surface and electrons are ejected from the metal. If the intensity of the light is increased, what will happen to the ejection rate and maximum energy of the electrons?

Question

Quizplus · Accepted Answer

Increasing the intensity of monochromatic light increases the number of photons hitting the metal surface per unit time, which increases the ejection rate of electrons. However, the maximum energy of the ejected electrons is determined by the frequency of the light, not its intensity, and remains the same.
