1. Over the entrance to a restaurant is mounted a strip of equally spaced light bulbs, as shown in the figure at the side. Starting at the left end, each bulb turns on in sequence for one-half second. Thus, a lighted bulb appears to move from left to right. After the last bulb on the right turns on, the apparent motion reverses. The lighted bulb then appears to move to the left, as part b of the drawing indicates. As a result, the lighted bulb appears to oscillate back and forth. Is the apparent motion simple harmonic motion? Explain.

Part A E A5.8-cm-thick layer of oil (n=1.46) is sandwiched between a 1.4-cm-thick sheet of glass and a 2.1- cm-thick sheet of polystyrene plastic (n=1.59). How long (in ms) does it take light incident perpendicular to the glass to pass through this 9.3-cm-thick sandwich? Express your answer in nanoseconds. ΜΕ ΑΣΦ
PROBLEMS 10.1 Faster than light. I stand 10 feet from a white wall, holding a laser pointer. The pointer makes a red dot on the wall directly in front of me. Then with a quick flick of my wrist (lasting only 0.1 second) I twist the laser pointer by 45°, and the red dot moves 10 feet in 0.1 second. I repeat the experiment standing 20 feet from a white wall, and the red dot moves 20 feet in 0.1 second. Finally, I repeat the experiment standing 186 000 miles from a white wall, and the red dot moves 186 000 miles in 0.1 second. In other words, the red dot moves 10 times faster than light speed. Why doesn't this motion violate the speed limit derived in this chapter?

As shown below, light from a vacuum is incident on a shard of Shawtonium (a newly discovered compound). The backside of the shard is up against an unknown material. When the light strikes the backside of the shard, total internal reflection occurs. The light then emerges from the side of the shard and resumes traveling through a vacuum. The index of refraction of Shawtonium is 1.8. Determine 0₁ & 0₂. vacuum 0₁ = 0₂ = unknown 8₂ shard 71° 36° 01...

Using the figure below, find the angles of refraction for a light ray passing from air into glass with the following angles of incidence: 5°, 10°, and 20°. 45 40 35 30 25 20 15 10 10 20 30 40 50 60 70 80 90 Angle in air (*) O10° %3D 020° Do you notice a trend in the resulting values? If so, describe it. O Doubling the angle of incidence approximately halves the angle of refraction. O Doubling the angle of incidence approximately doubles the angle of refraction. O Doubling the angle of incidence approximately quadruples the angle of refraction. There is no trend in the resulting values. Based on your observations, what would you predict the angle of refraction to be for an angle of incidence of 40°? How does your value compare with that inferred from the figure? () ssed u asuy

At the very end of Wagner's series of operas Ring of the Nibelung, Brünnhilde takes the golden ring from the finger of the dead Siegfried and throws it into the Rhine, where it sinks to the bottom of the river. Part A Assuming that the ring is small enough compared to the depth of the river to be treated as a point and that depth of the Rhine where the ring goes in is 12.8 m, what is the area of the largest circle at the surface of the water over which light from the ring could escape from the water? Use 1.33 for the index of refraction of water. Express your answer in meters squared. A = —| ΑΣΦ ? m²

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
