The wave number of the shortest wavelength of absorption specturm of H-atom is (Rydberg constant `=109700cm^(-1)`)

A

`109700 cm^(-1)`

B

`3//4xx109700cm^(-1)`

C

`1//2xx109700cm^(-1)`

D

`9//10xx109700cm^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
The shortest wavelength correspondsto maximum energy `:.n_(2)=oo`
`barv=109700cm^(-1)1/(1^(2))-1/(oo^(2))=109700cm^(-1)`
