Albert Einstein proposed the idea the light exists of quanta of energy that he called photons.
Max Planck.
Light consists of discrete packets of energy called quanta. A single quantum of light is better known as a photon.
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
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.

Discrete packages of light energy are called photons. Photons are also the quanta of all other electromagnetic radiation, not just light.

There are numerous mathematically equivalent formulations of quantum mechanics. One of the oldest and most commonly used formulations is the transformation theory proposed by Cambridge theoretical physicist Paul Dirac, which unifies and generalizes the two earliest formulations of quantum mechanics, matrix mechanics (invented by Werner Heisenberg)and wave mechanics (invented by Erwin Schrödinger).
If the photon is having very less frequency (say v=1Hz) ,then the Energy of such photon will be the smallest one. It can be inferred that the smallest unit of light energy will correspond to the smallest frequency of such quanta. But from the uncertainty principle it limits the energy of a quanta.
yes. it travels as photons which are individual quantum of light, caused by the electrons losing quanta of energy
In 1900 Max Planck noted that the spectrum of black-body radiation could be easily explained if it was assumed that light came in quanta (his word) of energy, each equal to the frequency of light times a constant (since known as "Planck's Constant"). He did not propose that these quanta actually existed, only the mathematical fact that they could explain something that, until then, could not be explained. Albert Einstein noted that this same assumption also readily explained the photo-electric effect; and proposed that these quanta were real physical quantities. In 1926, Gilbert Lewis gave these quanta the name "photons." In 1927 Arthur Eddington whimsically described them as "wavicles."
Yes, it's basically the same thing. Light energy (for example) comes in quanta, or "packets", that can't be further subdivided. The quanta are identified with particles, known as "photons".
