Document Summary

Summary of concave mirrors (important information to write down in your crib sheet for the final) o o. Summary of convex mirrors (important information to write down in your crib sheet for the final: always creates a virtual image o. Flat surface: the focal length goes infinite. Specifically, do = 10. 0cm , f =15. 0cm: using lens equation, di = -30cm o. Example 9: a diverging lens with f = - (1 / 5. 5)m is 14. 0cm away from an object 4. 0mm high . Image distance: f = - 1 / (5. 5m) ; do = 0. 14m so di calculates to be. Magnification will be +0. 56 which will be under 1. Height => m= hi/ho ; hi = 2. 24mm. In the figure below, a mystery lens is hidden behind the green rectangle. Determine the type of lens and type of image. Above diagram is very similar to the ray diagram in the previous example.
