Hint: At the focal point, parallel incident rays converge. In this instance, the focal lengths of the upper and lower halves are different. Since the semi-convex lens in the upper half only has one side plane, it has a longer focal length than the bi-convex lens in the lower half. The intersection of the two rays is now higher on the optical axis because the incident ray from the upper half will converge at a greater distance than the incident ray from the lower part.
Complete step by step solution:
As we know, such data about the equi-convex lens so now let us start the solution of this question. At the focal point, parallel incident rays converge. In this instance, the focal lengths of the upper and lower halves are different. Since the semi-convex lens in the upper half only has one side plane, it has a longer focal length than the bi-convex lens in the lower half.
The intersection of the two rays is now higher on the optical axis because the incident ray from the upper half will converge at a greater distance than the incident ray from the lower part. Therefore, as we get the detail from above, the third structure is the correct answer for this question.
Hence, the correct option is (C).
Note: Now as in this question we get some details about convex lens so now we know some properties of convex lens. A straight beam of light converges through this lens. The center of this lens is thicker, and as we move outward, it becomes thinner.
