Best answer
Correct Answer - B
`hv=E((1)/(n_(1)""^(2))-(1)/(n_(2)""^(2))),`
लाइमन श्रेणी की सीमा आवृत्ति के लिये
`n_(2)=oo,n_(1)=1`
`"hv"_("L")=E((1)/(1^(2))-(1)/(oo))=E`
फुण्ड श्रेणी की सीमा आवृत्ति के लिये,
`"hv"_("p")=E((1)/(5^(2))-(1)/(oo))=(E)/(25)`
`:.(v_(P))/(v_(L))=(1)/(25)" अथवा "v_(P)=(v_(L))/(25).`
