A raisin1 is held between a thin converging lens and its focal point. In the following questions, the raisin is never moved farther from the lens than the focal point.a. As the raisin is moved away from the lens, towards the focal point, what happens to the size of its image formed by the lens? You may use a principal ray diagram or mathematics (or both!) to support your answer.b. For any position of the raisin between the lens and the focal point, is the image always larger than the raisin, always smaller, or does it depend on the location?
