Assertion: The transition of electrons

n_3 \rightarrow n_2

in H-atom will emit radiation of higher frequency than

n_4 \rightarrow n_3

.

Reason: Principal shells

n_2

and

n_3

have lower energy than

{n}_4

View answer and explanation

Correct option: B

If both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion.

Option B (If both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion.) is correct because both the assertion about the frequency of emitted radiation and the reason about energy levels are true, but the energy level difference is the direct cause of the frequency.
