In this video explains how light can have particle properties as well as wave properties. Newton is correct after all, light is composed of particles if the frequency and energy are high enough. Max Planck will show that light is not a continuous flow of energy but rather little chunks of discrete energy called quanta (quantum) and finds a relationship between frequency and energy that becomes know as Planck's constant (h). Albert Einstein uses this constant to explain the photoelectric effect and his theories. Einstein changed the name of the quantum to photon. Photons are quantized packets of energy found in light the higher the frequency the higher the energy and the more particle like the light becomes.
