Wavelength of light emitted from second orbit to first orbit in a hydrogen atom is

Options

  1. A6563 Å
  2. B4102 Å
  3. C4861 Å
  4. D1215 Å

Correct answer

D. 1215 Å

Step-by-step solution

Wavelength of light aligned & 1 =R ( 1 1^2 - 1 2^2 ) & 1 =1.097 10^7 3 4 & =1.215 10⁻⁷ ~m =1215 Å aligned
