If an electron in a hydrogen atom jumps from an orbit of level n =3 to orbit of level n =2 , then the emitted radiation frequency is (where R = Rydberg's constant, C = Velocity of light)

Options

  1. A3 RC 27
  2. BRC 25
  3. C8RC 9
  4. D5RC 36

Correct answer

D. 5RC 36

Step-by-step solution

array ll & 1 = R [ 1 n ₁^2 - 1 n ₂^2 ] & 1 = [ 1 2^2 - 1 3^2 ]= 5 36 R & f = c = 5 36 Rc array
