Using Bohr's postulates, derive the expression for the orbital period of the electron moving in the nth orbit of hydrogen atom.
Every atom consists of nucleus and suitable number of electrons revolved around the nucleus in circular orbits.
(ii) Electrons revolved only in certain non-radiating orbits called stationery orbits for which the total angular momentum is an integral multiple of h/2p where h is plank's constant.

L is the Angular momentum of the revolving electrons
(iii) Radiation occurs when an electron jumps from one permitted orbit to another. It is emitted when electron jumps from higher orbit to a lower orbit
i.e., E2 - E1 = hf, where f is fr
