Question

You are provided with a concave mirror, a convex mirror, a concave lens, and a convex lens. To obtain an enlarged image of an object you can use either

• A. Concave mirror or a Convex mirror
• B. Concave mirror or Convex lens
• C. Concave mirror or Concave lens
• D. Concave lens or Convex lens.

Answer 1

The correct option is B

Concave mirror or Convex lens

The explanation for the correct option:

In the case of option B

1. A mirror is formed when a hollow sphere is divided into pieces and the outside surface of each cut component is painted, with the interior surface reflecting light.
2. A straight beam of light is converged by a convex lens, which is thicker in the center and thinner as we travel towards the edges.
3. A concave mirror and convex lens form enlarged images.

Hence, option (B) is correct.

The explanation for incorrect options:

In the case of option A

1. For option A, the convex mirror forms a diminished image.
2. Hence, option A is incorrect.

In the case of option C

1. For option C, the concave lens forms a diminished image.
2. Hence, option C is incorrect.

In the case of option D

1. For option D, the concave lens forms a diminished image.
2. Hence, option D is incorrect.
