Question

The energy levels of an hydrogen atom are shown below. The transition corresponding to emission of shortest wavelength is

• A. A
• B. D
• C. C
• D. B

Answer 1

Answer: (B)

D

Answer 2

$ΔE=\frac{hc}{λ} ⇒ λ\alpha \frac{1}{ΔE}$
For shortest wavelength, energy gap should be maximum.
So, correct choice is transition from n = 3 to n = 1.
