Photoelectric effect and wave theory of light
http://vergil.chemistry.gatech.edu/notes/quantrev/node4.html WebSolution. Photoelectric can be only explained by assuming that light is made up of particle not wave because. There is no time lag b/w incident of radiation and ejection of electrons. If light were a wave than electrons will take some time to come out from metal because light wave of same energy would be distributed over large number of electrons.

The discovery of the photoelectric effect was one of the greatest achievements of Einstein's life, for which he received the Nobel Prize. Einstein was the first to suggest that light is both a wave and a particle. This is called the wave-particle duality of light.
