I think you mean the particle model of light...photons?!


You have the Photoelectric Effect and the Compton Effect.

In the Photoelectric Effect photoelectrons emitted by the surface of a metal have kinetic energy dependent upon the FREQUENCY #f# of the incoming photons suggesting the photons have/are "packets" of energy of value: #E=hf#.

In the Compton Effect particles "recoils" after being "stricken" by light as in a collision where momentum is conserved suggesting that light carries momentum as....a particle!
