Questions
An electron in hydrogen atom makes a transition where are principal quantum numbers of the two states. Assuming Bohr's 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 are
detailed solution
Correct option is D
The time period T of an electron in a Bohr orbit of principal quantum number n isT=4ε02h3n3me4 T∝n3 ∴ T1T2=n13n23 As T1=8T2 , the above relation gives n1n23=8 or n1=2n2 Thus the possible values of n1 and n2 are n1=2,n2=1 ; n1=4,n2=2;n1=6,n2=3, and so on.Talk to our academic expert!
