In the seventeenth century, two theories of light - (i) Newton's corpuscular theory and (ii) Huygens' wave theory - were proposed. In the early stages, Newton's theory was more widely accepted than Huygens' theory. Later on, however, it was realized that Newton's theory suffered from many drawbacks and led to conclusions which were contradictory to the experimental results. Therefore Newton's theory was discarded in favor of Huygens' theory.
The wave theory of light was proposed in 1678 by a Dutch physicist, Christian Huygens.
Sir Isaac Newton, held the theory that light was made up of tiny particles.
In 1803, Thomas Young studied the interference of light waves by shining light through a screen with two slits equally separated, the light emerging from the two slits, spread out according to Huygen's principle.
Later in 1815, Augustin Fresnel supported Young's experiments with mathematical calculations.
In 1900 Max Planck proposed the existence of a light quantum, a finite packet of energy which depends on the frequency and velocity of the radiation.
