In a sample of `H-` atom electrons make transition from `5^(th)` excited state to ground state, producing all possible types of photons, then number of lines in infrared region are

A

4

B

5

C

6

D

3

Text Solution

Verified by Experts

The correct Answer is:
C

maximum number of lines produced =`(6(6-1))/2=15`
out of these 15 lines.
5 lines belong to ultra violet region and 4 lines are in visible region and rest are in infrared region.
