For any given series of spectral lines of atomic hydrogen, let  Δv-=v-max-v-min  be the difference in maximum and minimum wave number in cm-1

The ratio Δv-Lyman/Δv-Balmar is

Options:

Answer:
D
Solution:

=vmax-vminlymanvmax-vminBalmar  

ν=1λ=Ech


=Emax-EminlymanEmax-EminBalmar 

E=hν, ν=Eh


=E1- E12E2- E23 


=13.6 11-1-13.6 11-1413.6 14-1-13.6 14-19


=1-0-1+1414-0-14+19 =1/41/9=94
