What will we be learning today?
How Do Convex Mirrors Work?
A convex mirror is curved like part of the outside of a sphere. It produces an image that is right-side up and much smaller than the object. Convex mirrors are used as side rearview mirrors in cars. They give a wide-angle view. However, the cars seem to be farther away than they really are. Convex mirrors are also used in stores as security mirrors to give a wide view of what's going on in the store.
Convex mirrors provide a wide-angle view.
The image lies behind the mirror and is smaller than the object. Note how ray 2 reflects back upon itself. Have you ever gone to a parade and missed almost everything because the people in front of you were taller than you? A simple periscope might have helped. Simple periscopes are tall tubes with mirrors inside that help you see over things that would otherwise block your view. Periscopes are also used in submarines to allow the subs to stay underwater while getting a look at what's going on above the water's surface. Let's Review What We Learned Today!
