Question

Match each transition of the hydrogen atom in Column I with the statements in Column II that are true for the emitted photon ( $E_{n} = - 13.6/ n^{2}$ eV) (a Column I entry may match more than one Column II entry):

Column I (Transition)	Column II (Statement)
(P) $n = 2$ to $n = 1$	(1) ultraviolet region
(Q) $n = 3$ to $n = 2$	(2) visible region
(R) $n = 5$ to $n = 3$	(3) infrared region
(S) $n = 6$ to $n = 5$	(4) belongs to the Paschen series
	(5) photon energy more than 10 eV
	(6) photon energy less than 1 eV

Choose the option with the correct matching:

TestHub · Accepted Answer

(P) 10.2 eV, ultraviolet (1, 5).

(Q) 1.89 eV, visible (2).

(R) $13.6 (1/9 - 1/25) = 0.97$ eV, infrared, ends at $n = 3$ so Paschen, below 1 eV (3, 4, 6).

(S) 0.166 eV, infrared (Pfund), below 1 eV (3, 6).

Correct matching: P to 1,5; Q to 2; R to 3,4,6; S to 3,6. Answer: (D).
