Question

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

(1) 2→ 1 

(2) 3→ 2 

(3) 4 →2 

(4) 5→ 4 

Answer 1

Correct option : (4) 5→ 4

Explanation :

Energy of infrared radiation is less than the energy of ultraviolet radiation. As shown below the energy released will be less in option (4) while the energy released will be more in option (1), (2) and (3). Hence option (4) is correct.

From this data we find that option (4) is the correct option.
