Experiment 9: concave and convex mirrors



The purpose of this experiment is to explore images formed by concave and convex mirrors.
Convex

The image is smaller and upright.  The object looks farther in the mirror. As you move closer to the mirror, the image becomes normal size.  As you move farther the object becomes much smaller.

Convex Worksheet

The magnification is 2.2cm/.8 =.37

The magnification of the real convex mirror is taken by dividing the measured the image height by the object height. 
6.2cm/12cm=.517

Concave

The image appears larger and upright. As you move closer to the mirror the image returns to normal.  If you move the object far enough the image is large and upside down.

The magnification is 2.2cm/.8 =.37

The magnification of the real convex mirror is
21.5cm/12cm=1.79
