Let T 1 and T 2 be the energy of an electron in the first and second excited states of hydrogen atom, respectively. According to the Bohr's model of an atom, the ratio T 1 : T 2 is

Options

  1. A4 : 1
  2. B4 : 9
  3. C9 : 4
  4. D1 : 4

Correct answer

C. 9 : 4

Step-by-step solution

Given T 1 ⇒ Energy of 1 st excited state For T 1 ⇒ n = 2 For T 2 ⇒ n = 3 We know, Energy ∝ 1 n 2 ∴   T 1 T 2 = 3 2 2 2 = 9 4
