A flat sheet of crystalline quartz has a thickness of 3.5 cm. It is on top of a flat sheet of diamond that has a thickness of 2.0 cm. Light strikes the crystalline quartz vertically and travels through hit and then during the diamond. In the time it takes the light to travel during the two sheets, how far would it have traveled in a vacuum?
