Physics Review Question Unit: Geometric Optics Year: 1997 Question#: 91 Question: As the object is moved from point C toward point F, the size of its image (1 ) decreases (2 ) increases (3 ) remains the same What is this question really asking? Explanation by: Clayton B [ Return to question menu ] Answer 1 decreases INCORRECT By comparing the changes in size of the image, it can be seen that the size doesn't decrease. return to top Answer 2 Increases CORRECT Refer back to answer 1 to compare the diagrams. In the second diagram, it's clear that the image is larger when the object approaches the focal point from point C. return to top Answer 3 Remains the same INCORRECT You should eliminate this answer first. The size of the image constantly changes. return to top What's this question really asking? Does the image become larger when it is placed closer to the focal point? return to top |
