Atoms And Nuclei Question 57

Question: The electron in a hydrogen atom makes a transition n1→n2 , where n1 and n2 are the principal quantum numbers of the two states. Assume the Bohr model to be valid. The time period of the electron in the initial state is eight times that in the final state. The possible values of n1 and n2 are [IIT 1998; KCET 2005]

Options:

A) n1=4, n2=2

B) n1=8, n2=2

C) n1=8, n2=1

D) n1=6, n2=3

Show Answer

Answer:

Correct Answer: D

Solution:

T∝n3 . Given Tn1=8,Tn2 , hence n1=2n2 Therefore, option (a) and (d) both are correct.
