The ratio of energies of the H-atom, in ...

The ratio of energies of the H-atom, in its first to second excited state is

A

`1 : 4`

B

`4 : 9`

C

`9 : 4`

D

`4 : 1`

Text Solution

Verified by Experts

The correct Answer is:
C
`E_(n) prop 1/n^(2)`
Thus, `E_(1)=E_(0)/4` & `E_(2)=E_(0)/9 :. E_(1)/E_(2)=9/4`
