This process is called the photoelectric effect (or photoelectric emission the photoelectric effect was first observed in 1887 by particle physics quantum. Einstein explained the photoelectric effect in 1905, but the full philosophical implications weren't understood until the early 1920's (or maybe they still. In the photoelectric effect, a photon ejects an electron from a material researchers have now used attosecond laser pulses to measure the time evolution of this effect.

Lamb 1969 states, a misconception which most physicists acquire in their formative years is that the photoelectric effect requires the quantization of the electromagnetic field for its explanati. Point out to the students that the photoelectric effect is apparently instantaneous however, the light must be energetic enough, which for zinc is in the ultraviolet region of the spectrumif light were waves, we would expect the free electrons to steadily absorb energy until they escape from the surface.
