Question

The transition from the state n = 4 to n = 3 in a hydrogen like atom results in ultraviolet radiation. Infrared radiation will be obtained in the transition from ______.

विकल्प

• 2 → 1

• 3 → 2

• 4 → 2

• 5 → 4

Answer 1

The transition from the state n = 4 to n = 3 in a hydrogen like atom results in ultraviolet radiation. Infrared radiation will be obtained in the transition from 5 → 4.

Explanation:

λ_IR > λ_UV also wavelength of emitted radiation λ ∝ `1/(Delta"E")`.
