What type of lens do humans have in their eyes?

Why does light refract when it encounters the glass in a lens?

• because it speeds up, which causes it to bend

• because it slows down, which causes it to bend

• because it hits a dense medium, which causes it to bounce off

• because it gets absorbed, which causes it to lessen in intensity

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.
