A linear gradient refractive index (linear GRIN) is a type of GRIN material where the refractive index changes linearly with distance. Suppose that the refractive index of a linear GRIN increases at a constant rate between 1.48 (point A) and 1.56 (point B). A and B lie on the horizontal axis and the distance separating points A and B is 3.5 cm. Calculate the time needed for an electromagnetic wave to travel between points A and B.
