A flat sheet of chrystalline quartz has a
thickness of 2.48 cm. It is on top of a flat sheet of fused quartz
that has a thickness of 1.50 cm. Light strikes the chrystalline
quartz 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?
