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 directio

Answer :

The correct option is (C) " 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 ".

Explanation :

It is given that, incident ray X passes parallel to the principal axis of a concave lens. In concave lens ( also known as the diverging lens ), the ray appears as it passed through the focus as shown in figure 1.

When incident ray Y passes parallel to the principal axis of a convex lens ( also known as the converging lens ), it will pass through the focal point of the lens as shown in figure 2.

Hence, the correct option is (C).
