*2. An object 3 mm high is placed 20 cm from a converging mirror whose radius of cur- vature is 20 cm. a) Where is the final image, and is it real or virtual? b) How big is the image, and is it erect or inverted? *3. John lives on a windy country road. It is difficult to pull out of the driveway onto the road since the road is curved and trees prevent him from seeing around the corner. He recently installed a large convex mirror at one of the curves to give him a wider angle of view. It has a focal length of -1.54 meters. Determine the magnification of an oncoming car located 35.8 m from the mirror. *4, An object 3 mm high is placed 50 cm to the left of a converging lens of focal length 40 cm. A second converging lens with a focal length 10 cm is placed 220 cm to the right of the first lens. Where is the final image? Is it real or virtual? What will be the image size? Is it erect or inverted? fi=40cm =10cm 3 mm - 50 cm - 220 em - *5. A pebble 1 cm tall is placed 40 cm to the left of a +5-diopter lens. A -5-diopter lens is placed 30 cm to the right of the first lens. Where will the final image be located, and will it be real or virtual? What will be the size of the final image, and will it be erect or inverted? P,=+5D ,=-5D
