A laser beam shines along the surface of a block of transparent material. (See the figure .) Half of the beam goes straight to a detector, while the other half travels through the block and then hits the detector. The time delay between the arrival of the two light beams at the detector is 6.10 ns. Part A What is the index of refraction of this material? n = -- ΑΣΦ Submit Request Answer ? n = ? -2.50 m- Detector

A flat sheet of ice (n = 1.309) has a thickness of 2.7 cm. It is on top of a flat sheet of crystalline quartz (n = 1.544) that has a thickness of 1.5 cm. Light strikes the ice perpendicularly and travels through it and then through the 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? Number i Units

White light is incident onto a 30° prism at the 40° angle shown in the figure. Violet light emerges perpendicular to the rear face of the prism. The index of refraction of violet light in this glass is 2.0% larger than the index of refraction of red light. (Figure 1) Figure White light 40⁰ 30° 1 of 1 Part A At what angle does red light emerge from the rear face?
