Light is incident normal to a liquid layer of refractive index 1.33 that lies on top of a flat flint glass. The light will take 3.73x10^-11 s of more time to traverse through these two layers than the same distance in air. Find the refractive index of flint glass if the widths of liquid and glass layers are 1.5cm and 1.0cm.
