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
(a) 5→2 (b) 4→1 (c) 2→5 (d) 3→2

Answer 1

The jumps of the electron for Bohr orbits in an atom of  hydrogen is from

third line from red end 2 ---> 5 transition.

option (C) is correct.

Explanation:

Here red end means it is a part of the visible region and obviously only blamer series corresponds to the visible region.

For Balmer series n1 = 2

• First line from red end 2 ---> 3 transition
• Second line from red end 2 ---> 4 transition
• Third line from red end 2 ---> 5 transition

Thus the jumps of the electron for Bohr orbits in an atom of  hydrogen is from

third line from red end 2 ---> 5 transition.
