The wavelength of the radiation emitted, when in hydrogen atom electron falls from infinity to stationary state 1 , would be (Rydberg constant .=1.097 10^7 ~m ⁻¹ )

Options

  1. A91 ~nm
  2. B9.1 10⁻⁸ ~nm
  3. C406 ~nm
  4. D192 ~nm

Correct answer

A. 91 ~nm

Step-by-step solution

1 = R [ 1 n ₁^2 - 1 n ₂^2 ]=1.097 10^7 ( 1 1 ) = 1 1.097 10⁻⁷ ~m
