Physics 212 2/7 HW Handout Name______________________ Spring 2003 Diverging Lens Due Wednesday 2/12 1) Diverging Lenses: An object is placed at different locations in front of a converging lens (at 17cm, 8cm, 4cm, and 2cm). The focal length of the lens is -4 cm. Do the following for each situation. a) Draw an accurate ray diagram showing the location, orientation, and size of the image for all four cases. b) Apply the thin lens equation and the magnification equation and find the image location and size mathematically for all four cases. You may show these calculations on the graph paper if you wish. Make sure your calculations agree with your ray diagram-watch out for minus signs!! 2) Describe below in words what happens to your

Unformatted text preview: image as you (the object) walk toward a diverging lens. Start very far away and walk all the way through the focal point to the lens. Be sure to discuss all the following points. Hint: Use your ray diagrams. a) How does the size of your image change? Is it ever inverted? b) What is the largest your image can be? Smallest? c) Is your image virtual or real? Does it switch from one to the other? If so, where? d) What happens to your image as you walk through the focal point?
