Calculate the wavalength of radiation emitted when electron in a hydrogen atom jumps from `n=oo` to n=1 .

Text Solution

Verified by Experts

`1/(lambda) =R(1/(n_1^2)-1/(n_2^2))`
or, `1/lambda=1.097xx10^7(1/1-1/oo)=1.097xx10^7`
or, `lambda=1/(1.097xx10^7)=911.6xx10^(-10)m`
`therefore lambda=911.6 "Å"`
