Question

A __ lens is sometimes called a converging lens because it ___. A) convex; makes parallel light rays curve outward or diverge. B) concave; makes parallel light rays travel at a faster speed than before they encountered the lens. Eliminate C) 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. D) concave; 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 1

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.

Step-by-step explanation:

A convex lens is also called converging lens because all light rays incidented on the lens and parallel to the principal axis converges at the focus at the other side after refraction.

A lens is a transparent medium where all light rays incident and passing through it converges after refraction. They converge at a point known as the principal focus or the focal point. No matter the number of rays incident on the lens (i.e striking the lens) they all CONVERGES at the FOCAL POINT.
