Question
State Bohr postulate of hydrogen atom that gives the relationship for the frequency of emitted photon in a transition.
Advertisements
Solution
According to Bohr's postulate: electron might make a transition from one of its specified non-radiating orbits to another of lower energy. When it does so, a photon is emitted having energy equal to the energy difference between the initial and final state.
