Calculate the wave number of photon emitted during transition from the orbit n =2 to n =1 in hydrogen atom ( R _ H =109677 ~cm ⁻¹ )

Options

  1. A72740 ~cm ⁻¹
  2. B92820 ~cm ⁻¹
  3. C82258 ~cm ⁻¹
  4. D83560 ~cm ⁻¹

Correct answer

C. 82258 ~cm ⁻¹

Step-by-step solution

aligned & V = R _ H ( 1 n ₁^2 - 1 n ₂^2 ) & =109677 ( 1 1^2 - 1 2^2 ) & =82,257.75 ~cm ⁻¹ aligned
