(A) The $U.V.$ region (Lyman series) corresponds to electronic transitions ending at the $n = 1$ energy level.Since the electron is transitioning from the $6^{th}$ orbit to the $3^{rd}$ orbit,all possible transitions occur between $n = 6$ and $n = 3$.None of these transitions result in an electron reaching the $n = 1$ level.Therefore,the number of spectral lines in the $U.V.$ region is $0$.

In the hydrogen spectrum,if an electron transitions from the $6^{th}$ orbit to the $3^{rd}$ orbit through multiple steps,what is the total number of spectral lines in the $U.V.$ region?
