Physics Review Question Unit: Lens Year: 1992 Question#: 94 Question: An object 0.080 meter high is placed 0.20 meter from a converging (convex) lens. If the distance of the image from the lens is 0.40 meter, the height of the image is (1 ) 0.010 m (2 ) 0.040 m (3 ) 0.80 m (4 ) 0.16 m What is this question really asking? Explanation by: Larissa B [ Return to question menu ] Answer 1 0.010 m INCORRECT return to top Answer 2 0.040 m INCORRECT return to top Answer 3 0.080 m INCORRECT return to top Answer 4 0.16 m CORRECT this formula can be found on the regents reference tables: substituting in the object size: 080 m, the object distance: .2 m, and the image distance .4 m, we find the image size: 0.16 m return to top What's this question really asking? Use the image size ratio. return to top
