The kitten, Simba (Fig. A) and the kitten, Bella (Fig. B) are inspecting a goldfish swimming inside a round aquarium filled with water (nwater = 1.33). The magnitude of the radius of the round surface of the aquarium is 16 cm. The kittens are in air (nair=1.00). In order to calculate the apparent depth of the fish as viewed by the kittens, you need to use the equation shown in Fig. C. Identify the following (Please note that I am not asking you to do the calculation) n₁ P Fig. A + n₂ 9 = (n₂-n₁) R Fig. C Fig. A: n₁ = Fig. B: n₁ = ; n₂ = _; n₂ = Fig. B ; R = ; R =

A dedicated sports car enthusiast polishes the inside and outside surfaces of a hubcap that is a section of a sphere. When he looks into one side of the hubcap, he sees an image of his face 10.9 cm in back of it. He then turns the hubcap over, keeping it the same distance from his face. He now sees an image of his face 28.3 cm in back of the hubcap. (a) How far is his face from the hubcap? (b) What is the magnitude of the radius of curvature of the hubcap? cm Submit Answer 14 Deimant DETAILS MY NOTES SEDCD10 .22 0.010. ASK YOUR TEACHER

An Unidentified Flying Object. You and your team spot a strange object hovering over the open ocean in broad daylight. You have nothing to reference in order to estimate its distance, height, or size, but you get the idea to use a concave mirror from a signal light. You disassemble the light, extract the mirror, and point it at the sun. You measure the distance to the sun's image from the center of the mirror to be 3.406 m. You then point the mirror at the object and find that its image forms 3.441 m from the center of the mirror. The angle between the line of sight to the object and the horizontal is 28.5 ° (a) What is the distance between you and the object? (b) What is the height of the object above the ground? (c) If the width of the object's image is 11.8 cm, what is the width of the object? (a) Number 1 (b) Number (c) Number i Units Units Units
