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, begin mathsize 14px style straight E equals hc over straight lambda end style
where, c is the velocity of light h is universal constant called Planck's constant of action.
