The third line of the Balmer series, in the emission spectrum of the hydrogen atom, is due to the transition from the

Options

A. fourth Bohr orbit to the first Bohr orbit
B. fifth Bohr orbit to the second Bohr orbit
C. sixth Bohr orbit to the third Bohr orbit
D. seventh Bohr orbit to the third Bohr orbit.

Answer

B

Explanation

In Balmer series, `n_(1)`= 2 and `n_(2)`= 3, 4, 5 So, third line arises by the emission of `5^(th)` orbit to `2^(nd)` orbit.
