The ratio of energies of photons produced due to transition of electron of hydrogen atom from its (i) second to first energy level and (ii) highest energy level to second energy level is

Options

  1. A6:1
  2. B3:1
  3. C12:1
  4. D8:1

Correct answer

B. 3:1

Step-by-step solution

Let E₁ be the energy of the first energy level Then E₂= E₁ 4 Highest level E _ =0 E ₂- E ₁= E ₁ 4 - E ₁=- 3 4 E ₁E_ -E₂=0- E₁ 4 =- E₁ 4 E₂-E₁ E_ -E₂ =3
