Assertion : The transition of electrons `n_(3) to n_(2)` in H-atom will emit radiation of higher frequency than `n_(4) to n_(3)`.
Reason : Principal shells `n_(2)` and `n_(3)` have lower energy than `n_(4)`.

Options

A. If both (A) and (R) are correct and (R) is the correct explanation of(A).
B. If both (A) and (R) are correçt, but (R) is not the correct explanation of (A).
C. If (A) is correct, but (R) is incorrect.
D. If both (A) and (R) are incorrect.

Answer

B

Explanation

The difference between the energies of adjacent energy levels decrease as n value increases. Thus, for H-atom. `E_(2)-E_(1) gt E_(3)-E_(2) gt E_(4) -E_(3)`..............
