The Rydberg constant for hydrogen is `1.097xx10^(7)m^(-1)`. Calculate the short and long wavelength limits of Lyman series.

Text Solution

Verified by Experts

The correct Answer is:
`911.6Å, 1215Å`

for short wavelength limit, energy is maximum `n_(1)=1, n_(2)=oo`
and for long wavelength limit, energy is minimum `n_(1)=1, n_(2)=2`
