B)increase in the light's intensity
C)increase in the light's wavelength
D)decrease in the light's frequency
E)decrease in the light's intensity

Question

Quizplus · Accepted Answer

The kinetic energy of photoelectrons increases with a decrease in the light's wavelength, according to the photoelectric effect, where shorter wavelengths (higher frequency) photons have more energy to impart to the electrons.
