Question

highest wave number of spectral line in hydrogen spectrum is equal to
​

Answer 1

Answer:

Wave number of spectral line in emission spectrum of hydrogen,

vˉ=RH(n121−n221) ...(i)

Given, vˉ=98RH

On putting the value of vˉ in Eq. (i), we get-

98RH=RH(n121−n221)

98=(1)21−n221

98−1=n221

31=
