Question 180 • (OC27) MATH COLL ALGEBRA-1200710-S1-Degele-VOL7006P

Incident ray X passes parallel to the principal axis of a concave lens. Incident ray Y passes parallel to the principal axis of a convex lens.

Answer

Ray X continues moving in the same direction, and ray Y refracts and passes through the focal point located behind the lens.

Both rays refract and move as though they passed through the focal point.

Ray X appears as though it passed through the focal point in front of the lens, and ray Y passes through the focal point on the other side of the lens.

Both rays continue moving in the same direction.

Explanation

A ray parallel to the principal axis bends outward when it passes through a concave lens, as though it came from the focal point in front of the lens. A ray parallel to the axis bends inward through a convex lens and passes through the focal point on the other side. Therefore, choice C is correct.
