Question

Draw the line spectrum of hydrogen atom when an electron drops from n=5

to ground state​

Answer 1

Explanation:

If the electron jumps from n

2

=5 to n

1

=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.
