A flat sheet of sodium chloride has a thickness of 2.50 cm. It is on top of a flat sheet of fused quartz that has a thickness of 1.26 cm. Light strikes the sodium chloride perpendicularly and travels through it and then through the fused quartz. In the time it takes the light to travel through the two sheets, how far (in cm) would it have traveled in a vacuum?
