WebBohr proposed that in an atom electron is revolving around the nucleus in a definite circular path called orbits or shells. These orbits are called ‘stationary orbits’ and each orbit or shell possesses fixed energy. The energy levels are represented by an integer called quantum numbers where n = 1, 2, 3,..... Webwhat de broglie did was he included his wave nature principle in bohrs 2nd prostulate. He imagined the circumference of the orbit as a string and extending it in a straight line applied his concept and derived the same equation of angular momentum as bohr.
