Concave Convex Lenses

How does a concave lens differ from a convex lens?

• A convex lens is another way to describe a plane mirror; a concave lens is curved

• A concave lens is curved inward on both sides; a convex lens is on only one side

• A convex lens has a thick center and thin edges, a concave lens has a thin center and thicker edges

• A convex lens has a thin center and thick edges. a concave lens has a thick center and thinner edges

The point where the rays meet is known as....

• Fire
