Solution

When the excited electron of an H atom in n = 6 drops to the ground state, the following transitions are possible:

Hence, a total number of (5 + 4 + 3 + 2 + 1) 15 lines will be obtained in the emission spectrum.

The number of spectral lines produced when an electron in the nth level drops down to the ground state is given by `(n(n-1))/2`

Given,

n = 6

Number of spectral lines =` (6(6-1))/2 = 15`
