(B) The infrared region in the hydrogen spectrum includes the Paschen,Brackett,and Pfund series.For transitions from $n_2 = 6$ to $n_1 = 3$:$1$. Paschen series $(n_1 = 3)$: Transitions from $n_2 = 6, 5, 4$ to $n_1 = 3$. Number of lines = $6 - 3 = 3$.$2$. Brackett series $(n_1 = 4)$: Transitions from $n_2 = 6, 5$ to $n_1 = 4$. Number of lines = $6 - 4 = 2$.$3$. Pfund series $(n_1 = 5)$: Transition from $n_2 = 6$ to $n_1 = 5$. Number of lines = $6 - 5 = 1$.Total number of lines in the infrared region = $3 + 2 + 1 = 6$.

In the hydrogen spectrum,if an electron transitions from the $6^{th}$ orbit to the $3^{rd}$ orbit,what is the total number of spectral lines observed in the infrared region?
