Figure shown five energy levels of an atom , one being much lower than the other four. Five transitios between the levels are idicated, each of which produces a photon of definite energy and frequency.
Which one of the spectrum below best corresponding to the set of transition indicated?

Options

A.
B.
C.
D.

Answer

D

Explanation

The first three transition from the left fall in the Lyman series of the hydrogen spectrum which corresponds to ultraviolet radiation.
The fourth transion fall in the Balmer series of the spectrum which corresponds to the visible light emission .
Thus, frequencies of the last two transition are closed to each other on the extreme left of the frequencies spectrum whereas the frequencies of the first three transition are closer to one another and fall on the right corner of the frequencies spectrum. The spectrum of the transition is thus best represented in diagram
