For light at a wavelength of λ1 = 656.3 nm

For light at a wavelength of λ1 = 656.3 nm water (at 20° C) has an index of n= 1.3311. At a wavelength of λ2 = 89.3 nm water has an index of n2 = 1.333 0. Determine the approximate value of the group velocity of light in water. Is v̅ > vg? [Hint: Reread Problem 7.36, approximate the differentials by finite differences, and remember the little ω̅ in the definition of vg. Be careful of the slope of n versus λ.]
