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

A

`2 rarr 1`

B

`3 rarr 2`

C

`4 rarr 2`

D

`5 rarr 4`

Text Solution

Verified by Experts

The correct Answer is:
D
Since, `("frequency")_(UV) gt ("frequency")_(IR) rArr lamda_(UV) lt lamda_(IR) and lamda prop (1)/(Delta E ("Change in energy")) [ " as " E= (hc)/(lamda)]`
For greater value of `lamda`, energy gap should be less Hence, transition from `5 rarr 4`
