Question

An electron in a hydrogen atom makes a transition n₁→ n₂ , where n and n are the principal quantum numbers of the two states. Assume Bohr model to be valid.

Match the following column :

List - I	List - II
(P) The electron emits an energy of 2.55 eV	(1) $n_{1} = 2, n_{2} = 1$
(Q) Time period of the electron in the initial state is eight times that in the final state	(2) $n_{1} = 4, n_{2} = 2$
(R) Speed of electron become two times	(3) $n_{1} = 5, n_{2} = 3$
(S) Radius of orbit of electron becomes $4.76 \overset{˚}{A}$	(4) $n_{1} = 6, n_{2} = 3$
