Problem
Two kinds of glass have these refractive indices:
Glass P: μv=1.55, μr=1.51
Glass Q: μv=1.66, μr=1.60
Both have the same mean refractive index μ=1.53 for yellow light. Which glass has the greater dispersive power?
(a) Cannot be decided with the given data
(b) Glass Q only
(c) Glass P only
(d) Both are equal
