which observation provided albert einstein the clue that he needed to explain the photoelectric effect?\no light is made up of extremely small particles.\no particles that are emitted from a strip of metal are electrons.\no shining light on a metal strip produces emissions.\no energy of electrons depends on lights frequency, not intensity.

Answer

Brief Explanations:

Einstein's explanation of the photoelectric effect was based on the fact that the energy of ejected electrons depends on the frequency of the incident light, not its intensity. This observation contradicted classical wave - theory of light and led him to propose the photon concept.

Answer:

Energy of electrons depends on light's frequency, not intensity.
