Question

The number of spectral lines obtained in a transition from n = 4 to n = 1 are: (1) 6 (2) 8 (3) 4 (4) 2

Answer 1

Answer:

1)6 will be the correct option

Explanation:as per given question the transition is occurring from nth level i.e n=4 to ground state i.e n=1

for obtaining total spectral line use formula i.e

no of soectral line =n(n-1)/2

=4(4-1)/2

=12/2

= 6
