In Boh'r series of lines of hydrogen spectrum, the third line from the red corresponds to which one of the following inter orbit jumps of the electron for Boh'r orbit in an atom of hydrogen ?

A

`5 rarr 2`

B

`4 rarr 1`

C

`2 rarr 5`

D

`3 rarr 2`

Text Solution

Verified by Experts

The correct Answer is:
A
The lines at the red end belong to Balmer series These are obtained for jumps to `n=2` from outer orbits (1st line from `n=3` 2nd line from `n=4` 3rd line from `n=5`)
