<P> The time lag between the incidence of radiation and the emission of a photoelectron is very small, less than 10 second . </P> <P> The direction of distribution of emitted electrons peaks in the direction of polarization (the direction of the electric field) of the incident light, if it is linearly polarized . </P> <P> In 1905, Einstein proposed an explanation of the photoelectric effect using a concept first put forward by Max Planck that light waves consist of tiny bundles or packets of energy known as photons or quanta . </P> <P> The maximum kinetic energy K max (\ displaystyle K_ (\ max)) of an ejected electron is given by </P>

How does the idea of photons of light explain the photoelectric effect
