If an electron is present in n =6 level . How many maximum spectral lines would be observed in case of H atom-

A

10

B

15

C

20

D

25

Text Solution

Verified by Experts

The correct Answer is:
B
The no.of spectral lines is given by `(n(n-1))/(2)`
when n=6 then , the no. of spectral line `=(6xx(6-1))/(2)=(6xx5)/(2)=15`
