The electron in hydrogen atom is in the first Bohr orbit ( n =1 ). The ratio of transition energies, E ( n =1 n =3 ) to E ( n =1 n =2 ), is-

Options

  1. A32 / 27
  2. B16 / 27
  3. C32 / 9
  4. D8 / 9

Correct answer

A. 32 / 27

Step-by-step solution

E =13.6 ( 1 n ₁² - 1 n ₂² ) eV / atom E _ 1 3 = 1 1² - 1 3² 1 1² - 1 2² = .32 27 E _ 1 2
