Concave+Mirrors

Allyson Schmidt and Joe Walter


 * Objective:** Measure the focal length for a concave mirror
 * Apparatus:**
 * Computer/Mirror Simulation
 * Ruler
 * Procedure:**
 * 1) Open link []
 * 2) Place mirror and object anywhere in the simulation window
 * 3) With ruler, measure distance from object to mirror, and image to the mirrror
 * 4) Use thin mirror equation to verify focal length of mirror, then compare answer to given focal point
 * 5) Repeat two more times (at least one time place object within the focal length)


 * Analysis Questions:**
 * 1) What's the magnitude of the image when it is outside the focal point, when it is inside the focal point?
 * 2) Is the image real, or virtual when it is outside the focal point, when it is inside the focal point?
 * 3) Is the image upright or inverted when it is outside the focal point, when it is inside the focal point?


 * Graphical Analysis:**
 * No graphical analysis needed
