Problem 3 Light traveling through air strikes the boundary of some transparent material. The incident light is at an angle of 12 degrees, relative to the normal. The angle of refraction is 26 degrees relative to the normal. (nair is about 1.00) (a) Draw a clear physics diagram showing each part of the problem. (b) What is the angle of reflection? (c) What is the index of refraction of the transparent material? (d) What is the critical angle for this material? (e) What is Brewster's angle for this material and air?

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
