Question

how many Lymen spectral line observed coming from 6th excited state to first excited state?​

Answer 1

Answer:

Answer:

If the electron jumps from n2 = 5 to n1 = 1 then following are the transitions possible.

5→ 4

5→ 3

5→ 2

5 → 1

4 → 3

4→ 2

4→ 1

3 → 2

3→ 1

2 → 1

Hence there are 10 transitions and hence 10 spectral lines possible.

The general formula for the number of spectral lines emitted is
