(i) State Bohr'* quantization condition for defining stationary orbits. How does de Broglie hypothesis explain the stationary orbits ?
(ii) Find the relation between the three wavelength λ1,λ2 andλ3 from the energy level diagram shown below.
(i) Only those orbits are stable for which the
angular momentum, of revolving electron, is an integral multiple of h / 2π
[Alternatively
Circumference of permitted orbits are integral multiples of the wavelength λ.
