Unformatted text preview: Jim Guinn’s PHYS2212 Assignment #22 Solutions For each problem, draw a ray tracing diagram with the three primary rays, to scale, to find the image. Is it real or virtual, upright or inverted, and estimate its approximate magnification? Do not use the ThinLens Equation for these four problems! For problems 12, consider a converging lens with a focal length of 20.0cm. 1. Consider an object that is 2.00cm tall and 30.0cm from the lens. The image is real, inverted, and looks about twice the size of the object. 2. Consider an object that is 2.00cm tall and 10.0cm from the lens. The image is virtual, upright, and looks about twice the size of the object. For problems 34, consider a diverging lens with a focal length of 20.0cm. 3. Consider an object that is 2.00cm tall and 30.0cm from the lens. The image is virtual, upright, and looks about half the size of the object. 4. Consider an object that is 2.00cm tall and 10.0cm from the lens....
