Question

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

(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) sixth Bohr orbit to the second Bohr orbit

Answer 1

Correct option is (b) fifth Bohr orbit to the second Bohr orbit

Balmer series arises due to drop of electron to 2nd Bohr orbit, first line corresponds to n = 3 to n = 2, 2nd line n = 4 to n = 2 3rd line n = 5 to n = 2
