In this Physics video lecture in Hindi for class 11, 12 we explained Bohr's atomic model and Bohr's three postulates in hindi. Sometimes this model is also known as Bohr - Rutherford model. In his first postulate Niels Bohr assumed that electron can only move in certain allowed orbits where electrons do not emit any electromagnetic wave. His second postulate was, the angular momentum of any electron revolving around its nucleus can only be any integral multiple of h/2π, where h is Planck's constant whose value is 6.626 X 10^-34 J-s. In his third postulate he assumed that when electron jumps from one orbit to another, it either absorb or release energy equal to the difference between the energy levels of those orbits.
