Light is incident on an equilateral Lucite prism (n = 1.5) at an angle of 35°. Calculate the angle that the light leaves the prism. (66°) %3D ? 10. Freddie the fish shines his flashlight upward from under water. If Freddie shines his flashlight at an incident angle of 20°, at what angle does the light leave the water? (27°) В. A. Beyond what critical angle will the light no longer be able to leave the water? (48.8°) 11. From inside an aquarium a ray of light is directed at the glass so the angle of incidence, in water, is 30°. (a) Determine the angle of refraction when the ray emerges from the glass into the air.

The angle of incidence of a light beam onto a reflecting surface is continuously variable. The reflected ray in air is completely polarized when the angle of incidence is 49.8°. What is the index of refraction of the reflecting material? Need Help? Read It Watch It

A beam of light is incident from a liquid on the surface of transparent solid. The angle of incidence is 30°and the angle of refraction is 18°.   Draw clear physics diagram of the problem – one for each part of the problem (3 total).  label relevant angles.  Find the critical angle for this solid when it is surrounded by the liquid.    What is the angle between the reflected and refracted rays when the angle of incidence is 3°less than the critical angle?

Calculate the index of refraction in a substance where the speed of light is 1.2x108m/s? The angle of incidence from air into a substance is 30°. The angle of refraction in the substance is 18°. What is the speed of light in the substance?

Gaze into the Crystal Ball A set of coins is embedded in a spherical plastic paperweight having a radius of 5.0 cm. The index of refraction of the plastic is n, = 1.50. One coin is located 2.5 cm from the edge of the sphere (see the figure below). Find the position of the image of the coin. Light rays from a coin embedded in a plastic sphere form a virtual image between the surface of the object and the sphere surface. Because the object is inside the sphere, the front of the refracting surface is the interior of the sphere. d SOLUTION Conceptualize Because n, > n,, where n, = 1.00 is the index of refraction for air ,the rays originating from the coin in the figure are refracted away from the normal at the surface and diverge outward. Extending the outgoing rays backward shows an image point within the sphere. Categorize Because the light rays originate in one material and then pass through a curved surface into another material, this example involves an image formed by refraction…

A beam of light is incident on a square piece of glass with side s =  10.0 cm and index of refraction 1.50. The angles are shown in the figure to scale (you can count the blocks to measure them if you don't have a protractor). Where does the beam exit the glass? Assume the glass is in air (n = 1.00).

Determine the maximum angle ? for which the light rays incident on the end of the light pipe in the figure below are subject to total internal reflection along the walls of the pipe. Assume the light pipe has an index of refraction of 1.40 and the outside medium is air.
