Text Solution
Verified by Experts
The correct Answer is:
B
KEY CONCEPT : `E = R hc [(1)/(n_(1)^(2)) - (1)/(n_(2)^(2))]` `E` will be maximum for the transition for which `[(1)/(n_(1)^(2)) - (1)/(n_(2)^(2))]` is maximum for the third transition I,e `2 rarr 1 , 1 `mantion represents the absorption of energy
