Expert Answer:
Quantum theory was enunciated by Max Planck.
Light travels in the form of minute packets of energy which are known as quanta or photons. When a substance is excited, it emits light not as a continuous wave but it throws out energy in the form of protons of definite energies depending upon the wavelength (i.e., colour) of light.
Energy of one quantum, 
where, c is the velocity of light h is universal constant called Planck's constant of action.
