Write down of hydrogen spectrum .

Text Solution

Verified by Experts

The Swedish spectroscopist Johannes Rydberg noted that all series of line in the hydrogen spectrum could be described by the following expression.
where `n_(1) =1,2,3`
`n_(2) = (n_(1) +1) (n_(1) +2) (n_(1) +3)`
Rydberg constant for hydrogen `=109677 cm^(-1) = R_(H)`
The series of hydrogen spectrum are know by `n_(1)` value.
