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.

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

When light waves move from passing through air to passing through a glass lens when happens to them?

• They slow down and change direction

• They speed up and change direction

• They maintain the same speed and change direction

• They maintain their same speed and direction
