(1879 - 1955)
In the year 1905, Einstein elaborated on the
experimental results of Max Planck who noticed that electromagnetic
energy seemed to be emitted from radiating objects in quantities
that were discrete.
The energy of these emitted quantities- the
so-called light-quanta- was directly proportional to the frequency
of the radiation which was completely contrary to classical
electromagnetic theory, based on Maxwell's equations and the laws of
Einstein used Planck's quantum hypothesis to
describe visible electromagnetic radiation, or light. According to
Einstein's viewpoint, light could be imagined to consist of discrete
bundles of radiation.
