Einstein concept to explain the
Concept introduction:
According to photo electric effect, the light moves in the form of packets of energy, called photons. On the basis of quantum nature of light this effect is explained. The particles's nature of light is explained by photoelectric effect.

Answer to Problem 12SSC
Depending on Planck’s constant Einstein calculated the value of photon’s energy.
Explanation of Solution
In 1905 to explain photoelectric effect, Albert Einstein proposed dual nature of light. A light beam exhibits wavelike and particle-like nature. The energy of a photon is the product of Planck’s constant and the frequency. Energy of photon is
Wave origin of light is not explained by the photoelectric effect.
