Question

calculate energy of photon for H- atom emitted when electron jumps from 5th excited state to 2nd state​

Answer 1

Answer:

Correct option is

A

4

No. of lines =∑(n

2

−n

1

)

=∑(6−2)

=∑4

=∑

Balmer

=10

No. of spectral lines in Balmer series will be in visible range.

Hence no. of spectral lines in visible range will be 4.

Solution:- (A) 4 is correct
