Solution
The correct option is A
Convex lens:
- A convex lens is one that curves outward.
- The thickness at the center of a convex lens is greater than the thickness at the lens's edges.
- Converging lenses are convex lenses. They can focus a parallel beam of light on a single point.
- The lens in the human eye is an excellent example of a convex lens.
- A magnifying glass is another example of a convex lens that is commonly used to correct hypermetropia or long-sightedness.
- After refraction, the incident ray passing through F in the convex lens is parallel to the principal axis.
Hence, Option(A) is correct.
