PHY2054 Section 5887 Quiz 9: Ch 23 November 16, 2011 NAME UFID Show all your work step by step. 1. For a real object, what is the property of the image formed by a diverging lens? (a) It’s always virtual and inverted. (b) It’s always virtual and upright. (c) It’s always real and upright. (d) It’s always real and inverted. (e) It can be real or virtual, inverted or upright, depending on the object distance. (0.5/5) This is the multiple-choice question 10. 2. A glass plate ( n = 1 . 6) rests on the bottom of an aquarium tank. The plate is 10 . 00 cm thick (vertical dimension) and covered with some liquid ( n = 1 . 4) with a depth of 21 . 0 cm. Calculate the apparent thickness of the plate as viewed from above the liquid. (Assume nearly normal incidence of light rays.) (1.5/5) Solution: Problem 26. Answer: The apparent thickness is 10 / 1 . 6 = 6

Unformatted text preview: . 25 cm. 3. The object is midway between the lens and the mirror. The mirrors radius of curvature is 20 . 0 cm, and the lens has a focal length of-15 . 0 cm. Considering only the light that leaves the object and travels ﬁrst towards the mirror, locate the ﬁnal image formed by this system. (a) Find where the image is formed. ( e.g. xxx cm to the right of the lens ) (1.5/5) (b) Is the image real or virtual? If you don’t know how to calculate it, draw the ray diagram to ﬁnd the answer.(0.5) (c) What is the overall magniﬁcation of the image? (0.5/5) (d) Is it upright or inverted? If you don’t know how to calculate it, draw the ray diagram to ﬁnd the answer. (0.5) Solution: Problem 52. (a) 37 . 5 cm to the right of the lens. (b) virtual. 2 (c) M = 6. (d) upright....
