							Wave no. = R [1/n1^2 - 1/n2^2] = 1/wavelengthTo find ratio of longest wavelength of Him Lyman and shortest of He+ in balmer series just find ratio of wave no. Of He+ to the H= R [1/2^2 - 1/~]/R [1/1^2 - 1/2^2]~= infinityLongest wave length when n2=n1+1And shortest when n2=~So ratio comes out to be 1:3

1/LAMDA = RZ^2(1/22 - 1/32)
                  = R×4×(5/36)
                  = 5/9R
 
So the ratio is 5/9
This is the Right Answer
