In Bohr's theory of Hydrogen atom, the electron jumps from higher orbit n to lower orbit p . The wavelength will be maximum for the transition

Options

  1. An = 5 t o p = 4
  2. Bn = 4 t o p = 3
  3. Cn = 3 t o p = 2
  4. Dn = 2 t o p = 1

Correct answer

A. n = 5 t o p = 4

Step-by-step solution

According to Bohr's theory the wavelength of radiation emitted is given by 1 λ = R 1 n i 2 - 1 n f 2 For n i = 5 a n d n f = 4 , the wavelength emitted will be longest as energy difference ∆ E = E 5 - E 4 is very small.
