When the electron in hydrogen atom jumps from fourth Bohr orbit to second Bohr orbit, one gets the (a) second line of Balmer series (b) first line of Balmer series (c) first line of Pfund series (d) second line of Paschen series

Answer: (a). Lower level n = 2 means the Balmer series. 3 → 2 is the first line, 4 → 2 is the second line. So the answer is (a) second line of Balmer series.

When the electron in hydrogen atom jumps from fourth Bohr orbit to second Bohr orbit, one gets the

Show answer and solution

Answer: (a)

Lower level $n = 2$ means the Balmer series.
$3 \to 2$ is the first line, $4 \to 2$ is the second line.
So the answer is (a) second line of Balmer series.
