How Deep Is the Goldfish? Where Is the Image? A tank whose bottom is a mirror is filled with water to a depth of 20.7 cm . A small fish floats motionless 6.40 cm under the surface of the water. Learning Goal: To understand how to use ray tracing to determine image location and size for a convex lens. httpa-//sexs ment Print View ?assignmentID-9841222 Part A What is the apparent depth of the fish when viewed at normal incidence to the water? 3/11/22, 12:26 PM Homework 9 Express your answer in centimeters. Use 1.33 for the index of refraction of water. Ray tracing is one way to determine the location and size of an image for bject. The thin long added formed by a lens. Ray tracing allows you to follow the path of a few principal rays originating from a point on the imaged object. The thin lens approximation simplifies ray tracing by ignoring details of light propagation inside the You did not open hints for this part. ANSWER: the principal rays emitted from a single point on an object engineered at's piano is axis to a single focal point on the opposite side of the lens. It mining the location and size of a real image of the object. The most useful principal rays for converging lenses are cm Pray is directed parallel to the axis of the lens. It emerges from the lens directed toward the focal point on the side of the lens 2. The M ray is directed toward the midpoint 3. The Fray is directed toward the focal point on the same side of the lens as the object. it emerges from . It emerges from the lens directed parallel to the Part B What is the apparent depth of the reflection of the fish in the bottom of the tank when viewed at normal incidence? Part A Express your answer in centimeters. Use 1.33 for the index of refraction of water. Trace the Pray and Mray from the tip of the ob enough to majorphe segment on the opposite side). The points labeled F are the focal points of the lens. Be of the Pray on the same side You did not open hints for this part. Draw the vector of the vectors will be graded. ANSWER: You did not open hints for this part. ANSWER: cm 2 Problem 19.26 No elements selected A 1.95-m-tall diver is standing completely submerged on the bottom of a swimming pool, in 3.00 m of water. You are sitting on the end of the diving board, almost directly over her. Part A How tall does the diver appear to be? Express your answer with the appropriate units. NSWER: Problem 19.31 N' = An object is 34 cm in front of a diverging lens with a focal length of -17 cm. Part A Problem 19.28 Use ray tracing to determine the location of the image Express your answer with the appropriate units. Enter positive value if the image is on the oth the image is on the same side. negative value it ANSWER: An object is 30 cm in front of a converging lens with a focal length of 10 cm. 8' = Part A Use ray tracing to determine the location of the image. Problem 19.63 Express your answer in centimeters. Enter a positive value if the image is on the other side from the lens and a negative value if the image is on the same side. ANSWER: Index of refraction of the glass prism in is 1.44. s' = cm 30 Problem 19.67 60% You need to use a 24-cm-focal-length lens to produce an inverted image four times the height of an object. Part A What is the smallest angle 6 for which a laser enuse of the glass prism? Express your answer in degrees. Part A 7/10 At what distance from the object should the lens be placed? W11/22. 12:26 PM Homework 9 Express your answer with the appropriate units. ANSWER: 61 min =
