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
A concave lens has an inward curved shape. It refracts light outward from the lens. They light rays spread apart as they exit the lens. Which represents a concave lens?
A
B
A and B
neither A or B
What do a prism, a magnifying glass, a microscope, and eyeglasses ALL have in common.

They refract light
They reflect light

A ____ lens is sometimes called a converging lens because it_____.
convex; makes parallel light rays curve outward or diverge
concave; makes parallel light rays travel at a faster speed than before they encountered the lens
convex, makes parallel light rays passing through it bend inward and meet (converge) at a spot just beyond the lens known as the focal point.
concave; makes parallel light rays passing through it bend inward and meet (converge) at a spot just beyond the lend known as the focal point.
