Question

In the Bohr's series of lines in the hydrogen spectrum, the fourth line in the visible region corresponds to which of the following inner orbit jumps

Answer 1

Answer:

Red means its a part of visible region. Balmer series cooresponds to visible region. In balmer series n1 =2  third line means  n2 -n1   =3 so  n2 =3+2=5.

For the third line from the red end, n=5. so, the transition will be 5→2
