Question 14

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

Accepted Answer

because it slows down, which causes it to bend

Answer

because it speeds up, which causes it to bend

Answer

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

Answer

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

Question 17

A ____ lens is sometimes called a converging lens because it_____.

Accepted Answer

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.

Answer

convex; makes parallel light rays curve outward or diverge

Answer

concave; makes parallel light rays travel at a faster speed than before they encountered the lens

Answer

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.
