Question

Which of the following ray diagrams is correct for the ray of light incident on a lens shown in Figure?

Fig. \( 10.7 \)

• A.

  

• B.

  

• C.

  

• D.

  

Answer 1

The correct option is A

Convex lens:

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

Hence, Option(A) is correct.
