If electron shows transition from `n _(2) =4` to `n_(1) =2` Then, number of fine lines in the spectral line according to Sommerfeld model is ?

When an electron do transition from n = 4 to n = 2, then emitted line in spectrum will be:

When an electron makes transition from n = 4 to n = 2, then emitted line spectrum will be

When an electron do transition from n = 4 to n = 2, then emitted line in spectrum will be:

Draw the Bohr- Sommerfeld model for n= 2

If an electron transits from n = 7 to n = 1 in a hydrogen atom then the maximum number of spectral lines that can form will be?

If an electron transits from n = 7 to n = 1 in a hydrogen atom then the maximum number of spectral lines that can form will be?

The transition of electron occurs in H-atom from 6^(th) to 3^(rd) orbit. The number of spectral lines given are

The Balmer series in the hydrogen spectrum corresponds to the transition from n_(1)=2 to n_(2)=3,4 ........ This series lies in the visible region. Calculate the wave number of line associated with the transition in Balmer series when the electron moves to n=4 orbit. (R_(H)=109677cm^(-1))
