Quantum Hypothesis
A hypothesis that some physical quantity can assume only a certain discrete set of values; examples are Planck's law, and the condition in the Bohr-Sommerfeld theory that the action integral of a system must be an integral multiple of Planck's constant.

In 1900, Planck hypothesizied that light energy is quantized in the same way matter is. He stated that light isn't a continuous beam of energy. Instead, the beam of light is actually millions upon billions of small discrete packets of energy called quanta. Einstein recogized that these quanta of light behave much like tiny particles of matter. Each quantum of light is called a photon.
