how many uses do you know of concave and convex mirrors?
Convex and concave mirrors are used for more things than I can even
begin to count. Basically, they are used any time you want to make
something's reflection look bigger or smaller. You've probably seen
things like this in carnival fun-houses, where you look in different
mirrors and see yourself as really big or really small. A very common
use for concave mirrors is in telescopes
, and convex mirrors are sometimes used for home decorating
