" Energy is present in small packets which are also characterized for having the same amount of energy same as that of the source of its radiation, these small packets are called as Quanta"
Explanation:
When considering light as made up of individual "pieces," each characterized by a particular amount of energy, the pieces are called quanta.
As it is the basic coin or currency used by any body which posses energy to make a change, during any level of interaction with other material.
And such phenomenon which occurs is termed as Quantization, as it is fact that energy exists in the quantized form. As each bit of the energy posses some limited amount of energy inside it required for bringing any physical change in it.
Max Planck was the one who performed research based on quantum physics, and generated the quantum theory in physics.
