Question
In Bohr series of lines of hydrogen spectrum, the third line from the red end corresponds to which one of the following inter-orbit jumps of the electron for Bohr orbits in an atom of hydrogen
Options
A.5 → 2
B.4 → 1
C.2 → 5
D.3 → 2
Solution
The lines falling in the visible region comprise Balmer series. Hence the third line would be n1 = 2, n2 = 5 i.e. 5 → 2.
