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. how do the rays behave differently after passing through each lens? 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.
Answer
Brief Explanations:
For a concave lens, a ray parallel to the principal - axis appears to diverge from the focal point in front of the lens. For a convex lens, a ray parallel to the principal - axis refracts and passes through the focal point on the other side of the lens.
Answer:
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.
