1) A laser beam enters a 12.0 cm thick glass window at an angle of 66.0° from the normal. The index of refraction of the glass is 1.42. At what angle from the normal does the beam travel through the glass? I know this one is 40.04 degrees. I am stuck on this one: 2) How long does it take the beam to pass through the plate?
