Light striking a metal surface causes electrons to be emitted from the metal via the photoelectric effect.In a particular experiment to study the photoelectric effect, the frequency of the incident light and the temperature of the metal are held constant. Assuming that the light incident on the metal surface causes electrons to be ejected from the metal, what happens if the intensity of the incident light is increased?Check all that apply.The work function of the metal decreases.The number of electrons...
