Question

Calculate the number of spectral line produce during the transition of electron from n=3 to n=1.​

Answer 1

Explanation:

ni=3 and nf=1 v=3.29×10^15[1/n^2-1/n

Answer 2

Answer:

Electron can jump in two ways:-

1) Directly from 3 to 1.

In this case only one spectral line will be produced.

2)First from 3 to 2 then again from 2 to 1.

In this case two spectral lines can be produced.

there, total number of possible lines is 1+2 = 3
