Vedclass · Answer

(C) The wavelength of a spectral line in the Balmer series is given by the Rydberg formula: $\frac{1}{\lambda} = R \left( \frac{1}{2^2} - \frac{1}{n^2} \right)$,where $n = 3, 4, 5, \dots$ and $R$ is the Rydberg constant.For the Balmer series,the transition to the $n=2$ orbit determines the line:- For $n=3$ to $n=2$,we get the first line of the Balmer series.- For $n=4$ to $n=2$,we get the second line of the Balmer series.Therefore,the transition from the fourth orbit to the second orbit corresponds to the second line of the Balmer series.

When an electron in a hydrogen atom jumps from the fourth Bohr orbit to the second Bohr orbit,we get the:
