- The images show a glass of ice water filled to the brim. Will the water overflow when the ice melts? Explain answer.arrow_forwardAround 1965, engineers at the Toro Company invented a gasoline gauge for small engines diagrammed in Figure P25.32. The gauge has no moving parts. It consists of a flat slab of transparent plastic fitting vertically into a slot in the cap on the gas tank. None of the plastic has a reflective coating. The plastic projects from the horizontal top down nearly to the bottom of the opaque tank. Its lower edge is cut with facets making angles of 458 with the horizontal. A lawn mower operator looks down from above and sees a boundary between bright and dark on the gauge. The location of the boundary, across the width of the plastic, indicates the quantity of gasoline in the tank. (a) Explain how the gauge works. (b) Explain the design requirements, if any, for the index of refraction of the plastic.

- An cylindrical opaque drinking glass has a diameter 4 cm and height h, as shown in the figure. An observer's eye is placed as shown (the observer is just barely looking over the rim of the glass). When empty, the observer can just barely see the edge of the bottom of the glass. When filled to the brim with a transparent liquid, the observer can just barely see the center of the bottom of the glass. The liquid in the drinking glass has an index of refraction of 1.15.

- You sight along the rim of a glass with vertical sides so that the top rim is lined up with the opposite edge of the bottom (Fig.a). The glass is a thin-walled, hollow cylinder 16.0 cm high. The diameter of the top and bottom of the glass is 8.0 cm. While you keep your eye in the same position, a friend fills the glass with a transparent liquid, and you then see a dime that is lying at the center of the bottom of the glass (Fig.b). What is the index of refraction of the liquid?arrow_forwardA layer of liquid-A water (n = 1.305) floats on liquid-B carbon tetra-chloride (n = 1.682) contained in an aquarium. What is the critical angle at the interface between the two liquids?arrow_forwardTo dress up your dorm room, you have purchased a perfectly spherical glass fishbowl to place on the windowsill. After placing the sand, decorations, and water in the bowl of diameter 40.0 cm, you transfer a single tropical fish from a plastic bag into the bowl. As you watch the fish, your roommate comes home. He watches the fish also and notices that the apparent size of the fish changes as it swims around in the bowl. Ignore the effect of the thin glass walls of the bowl; take only the water into consideration. (Assume the index of refraction of water is 1.33 and the index of refraction of air is 1.00.) (a) He is not taking a physics course, so he asks you to tell him the range of magnifications of the fish as it swims along a line from the back of the bowl along a line passing through the center of the bowl directly toward the observer. = 0.2 M M min max Combine the equations for the formation of an image for a curved refracting surface and its magnification. 0.33 x Combine the…arrow_forward
