Question

give the Bohr's frequency rule​

Answer 1

Explanation:

Bohr frequency condition. The law that the frequency of the radiation emitted or absorbed during the transition of an atomic system between two stationary states equals the difference in the energies of the states divided by Planck's constant.

Answer 2

The law that the frequency of the radiation emitted or absorbed during the transition of an atomic system between two stationary states equals the difference in the energies of the states divided by Planck's constant.
