So if an electron in a metal absorbs a photon of energy, it uses the energy in the following ways. The photoelectric effect has helped physicists understand the quantum nature of light and electrons. The concept of wave–particle duality was developed because of the photoelectric effect. Albert Einstein proposed the Laws of Photoelectric Effect and won the Nobel Prize For Physics 1921. Einstein's Equation \(\ref{Eq1}\) explains the properties of the photoelectric effect quantitatively. A strange implication of this experiment is that light can behave as a kind of massless "particle" now known as a photon whose energy \(E=h u\) can be transferred to an actual particle (an electron), imparting kinetic energy to it, just as in an elastic collision between to massive particles Photoelectric effect Explaining the experiments on the photoelectric effect.

Notes. 1. Photoelectric Effect is a phenomenon of emission of electrons from metal surfaces exposed to light energy of suitable frequency. Einstein's Photoelectric Equation and Laws of Photoelectric Emission are explained. Explanation of Instantaneity of Photoelectric Effect on the Basis of Einstein’s Photoelectric Equation: The photoelectric effect is an instantaneous process. There is no time lag between the incidence of light and the emission of the photo-electrons in other words, the surface begins to emit photo-electrons as soon as light falls on it. Einstein's Explanation Of Photoelectric Effect According to the wave theory, energy is uniformly distributed across the wavefront and is dependent only on the Wave theory says that light of any frequency should be capable of ejecting electrons.

In particular, it's interpretation by Einstein significantly contributed to the perception  Einstein argued that light was a wave that interacts with matter in the form of a packet of energy or a quantum of energy. This quantum of radiation was a photon   Einstein explained the photoelectric effect by saying that "light itself is a particle," and for this he received the Nobel Prize in Physics.
