What is the ratio of the energies of an hydrogen atom, when it is in the third and second excited states?

A

`9/16`

B

`9/4`

C

`16/9`

D

`4/9`

Text Solution

Verified by Experts

The correct Answer is:
A
For second and third excited state n=3 and 4 and
`E_n prop 1/n^2 therefore E_3/E_2 = 3^2/4^2 = 9/16`
