If http://homework.math.ucsb.edu/webwor...faee426371.png is the focal length of a lens and http://homework.math.ucsb.edu/webwor...fd8fbc7ea1.png is the distance of an object from the lens and http://homework.math.ucsb.edu/webwor...92bdd1a1a1.png is the distance of the image from the lens then (a) Solve this equation for the distance of the image in terms of the other two quantities. Simplify your answer and put the denominator of the simplified fraction into the answer box (notice the numerator) (b) If the focal length is http://homework.math.ucsb.edu/webwor...4bcf8a0ea1.png and the distance of the object from the lens is http://homework.math.ucsb.edu/webwor...6f13391e61.png what is the distance of the image from the lens? (c) If the focal length is http://homework.math.ucsb.edu/webwor...4bcf8a0ea1.png and the distance of the object from the lens is very large, for example http://homework.math.ucsb.edu/webwor...80dbc1f5f1.png what is the distance of the image from the lens approximately? (this explains the name focal length)
