The electron of a hydrogen atom makes a transition from the (n+1)^ th orbit to the n^ th orbit. For large n the wavelength of the emitted radiation is proportional to

Options

  1. An
  2. Bn^3
  3. Cn^4
  4. Dn^2

Correct answer

B. n^3

Step-by-step solution

If n₁=n and n₂=n+1 Maximum wavelength _ = n^2 (n+1^2 ) (2 n+1 R) Therefore, for large n , _ n^3
