Solution:

Einstein explained the phenomenon of photoelectric effect on the basis of Planck's quantum theory. According to which light travels in the form of small bundles or packets of energy called photons. Hence, photoelectric effect explains the particle nature of light. Also the photoelectric current or the rate of emission of photoelectrons is directly proportional to the intensity of the incident light.
