A coin is sitting at the bottom of a glass, 26.7 cm deep below the surface of a clear but unknown liquid. You look at the coin from overhead and with your unparalleled skill at determining distances, you observe it to appear to be 11.3 cm below the surface. What is the index of refraction of the liquid?

One of the world's largest aquaria is the Monterey Bay Aquarium. The viewing wall is made of acrylic and is 0.33 m thick, and the tank holds 1.2 million gallons of water. A ray of light is directed into the plastic from air at an angle of a = 75°.The indices of refraction for air, acrylic, and seawater are listed on the figure. Air Acrylic Seawater 1.00 1.50 1.37 ਅਰ 1) Calculate the angle that the ray will make when it enters the plastic. (Express your answer to three significant figures.) Submit 2) Calculate the angle that the ray will make when it enters the seawater. (Express your answer to three significant figures.) Submit

A glass optical fiber is used to transport a light ray across a long distance. The fiber has an index of refraction of 1.530 and is submerged in glycerin, which has an index of refraction of 1.473. What is the critical angle (in degrees) for the light ray to remain inside the fiber? Need Help? Read It

A 3.87 m long pole stands vertically in a lake having a depth of 2.07 m. When the Sun is 38.2o above the horizontal, determine the length of the pole's shadow on the bottom of the lake. Take the index of refraction for water to be 1.33.

John likes to collect marbles and places a rare marble in a block of plastic. It seems that the marble is 2.0 cm within the plastic. (Index of refraction of the plastic = 1.60) What is the actual distance of the marble beneath the surface?

Building contractors often install double-glazed windows to prevent thermal energy (heat) from entering or exiting a building. In addition to being effective insulators, such windows present interesting optical effects. 62.0 mm In the figure, a double-glazed window consists of two identical of glass (ng panes 1.54), each yg thick, separated by an air gap of ya = 49.6 mm. Use na = 1.00 for the index of refraction of air. = If light incident on the glass makes an angle of = 40.00° with respect to the glass, find the shift in path Ax as the light enters the room. Ax = 42.36 Incorrect glass air glass mm

You can determine the index of refraction of a substance by determining its critical angle. (a) What is the index of refraction of a substance that has a critical angle of 51.0° when submerged in carbon tetrachloride, which has an index of refraction of 1.461? (b) What would the critical angle be for this substance in air?

A laser beam is propagating within a piece of glass with refraction index n1 (1.9600x10^0). What is the critical angle of total reflection when it strike the interface to another medium with refraction index n2 (1.29x10^0).
