# determining the path of light

Determine the path light will travel in a region where the index of refraction is described by n(y) = 1+ae^(-by). Let the light start off at the origin (0,0) and go to the point (L,0). Determine the equation that must be solved to determine the constant in your path equation. (Call that constant k, then k is a function of a, b, and L).
