Name: ____________________________________ Class: ________________________________ Unit 4: Let Us Entertain You Homework Set 17 Active Physics Read each questions carefully and answer. Show all work. Scoring Guidelines: Correct answer and all work shown = 1 point Correct answer with no work shown = 1/3 point Incorrect answer with all work shown = 1/3 point Incorrect answer with no work shown = 0 point Missing/incorrect units = -1/3 point 1. The diagram below shows the letter P in front of a plane mirror. BTECH 2. In the diagram below, a source produces a light ray that is reflected a plane mirror. Which diagram best represents the image of P produced by the plane mirror? A) B) To an observer at point O the light appears to originate from point A) A C) B) B C) C D) D 3. A candle is located beyond the principal focus, F, of a concave spherical mirror. Two light rays originating from the same point on the candle are incident on the mirror, as shown in the diagram below. D) After reflecting from the mirror, the light rays will A) B) C) D) diverge to form a virtual image diverge to form a real image converge to form a virtual image converge to form a real image Ms. Quinones 4. The diagram below shows a light ray parallel to the principal axis of a spherical convex (diverging) mirror. Point F is the virtual focal point of the mirror and C is the center of curvature. BTECH 5. The image of a shoplifter in a department store is viewed in a convex (diverging) mirror. The image is A) B) C) D) real and smaller than the shoplifter real and larger than the shoplifter virtual and smaller than the shoplifter virtual and larger than the shoplifter 6. The image produced by a convex (diverging) mirror must be After the light ray is reflected, it will pass through point A) A B) C C) D A) B) C) D) real and erect real and inverted virtual and erect virtual and inverted D) F Ms. Quinones
