Using Rydberg's formula calculate the wavelength of spectral lines of the first members of the Lyman series and Balmer series. Share with your friends Share 0 Sanjay Upadhyay answered this Dear studentThe relation for wavelength is given by1λ=R1ni2-1nf2Now wavelengh of first member of Lyman series will be1λ1=R112-122=34R=34×1.09×107=0.8175×107or λ1=1.22×10-7 mAlso wavelengh of first member of Balmer series will be1λ2=R122-132=536R=536×1.09×107=0.15138×107or λ2=6.60×10-7 mRegards 6 View Full Answer
