Albert Einstein proposed the idea the light exists of quanta of energy that he called photons.
Light of is made up of a finite number of photons, or light quanta. The energy of each photon is proportional to the frequency of the light, and hence inversely proportional to the wavelength of the light. Red light has a longer wavelength than blue light, so the quantum of red light has less energy than the quantum of blue light.
photons
Discrete packages of light energy are called photons. Photons are also the quanta of all other electromagnetic radiation, not just light.
Max Planck.
Photons of light.

Quanta
Max Planck.
A quanta of light (one photon).
A quantum can have almost any energy. For example, light comes in pieces or quanta (the photons), but the individual pieces (photons) can have any energy, from near zero to an almost unlimited energy.
