The transtion from the state `n = 4 to n = 3 ` in a hydrogen like atom results in ultraviolet radiation Infrared rediation will be obtained in the transition from :

Options

A. `4 to 2`
B. `3 to 2`
C. `5 to 4`
D. `2 to 1`

Answer

C

Explanation

In the transition from n=4 to n=3 , ultraviolet radiations are produced . For infared radiations, smaller amounts of energy is required . For this the initial value of n should be greater than 4. Thus from the given options, the transition should be 5 to 4.
