Referring to the previous problem, realize that there is a region between each pair of absorption bands for which the Cauchy Equation (with a new set of constants) works fairly well. Examine Fig. 3.41: what can you say about the various values of decreases across the spectrum? Dropping all but the first two terms, use Fig. 3.40 to determine approximate values for for borosilicate crown glass in the visible.

Referring to the previous problem:

Augustin Louis Cauchy (1789-1857) determined an empirical equation for for substances that are transparent in the visible. His .expression corresponded to the power series relation

where the Cs are all constants. In light of Fig. 3.41, what is the physical significance of C₁?
