Question

What phenomena explain particle nature of light

Answer 1

Answer:

Particle Nature of Light. The emission of free electrons from a metal surface when the light is shone on it, it is called the photoemission or the photoelectric effect. This effect led to the conclusion that light is made up of packets or quantum of energy. ... Thus, the wave-particle duality of light came into the picture . Max Planck and others were studying the photoelectric effect and they found that certain types of metal and other materials will eject electrons when light shines on them. The light particle conceived by Einstein is called a photon. The main point of his light quantum theory is the idea that light's energy is related to its oscillation frequency (known as frequency in the case of radio waves).
