Question
Write the basic features of the photon picture of electromagnetic radiation on which Einstein's photoelectric equation is based.

Answer
The basic features of the photon picture of e.m. radiation are as follows:
i. Light is composed of discrete packets of energy called quanta or photons.
ii. Each photon carries an energy $E (=h \nu)$ and momentum $p (= h / \lambda)$, which depend on the frequency $\nu$ of the incident radiation and not on its intensity.
iii. During the collision of a photon with an electron, the total energy of the photon gets absorbed by the electron.
iv. Photoelectric emission from the metal surface occurs due to the absorption of a photon by an electron.
