Which of the following transitions in a hydrogen atom emits the photon of highest frequency?


        (a)    n = 2 to n = 1


        (b)    n = 2 to n = 6


        (c)    n = 6 to n = 2   


(d)    n = 1 to n = 2

(a)

Note: See the greatest energy difference and also see that the transition is from higher to lower energy level. Hence, it is highest in case of n = 2 to n = 1.

Dear Student,
Please find below the solution to your problem.

Highest frequency emissionwill be of maximum energy difference.
Energy difference is more in n=2 to n=1 than n=6 to n=2

Thanks and Regards
