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

विकल्प

• concave mirror or convex mirror.

• concave mirror or convex lens.

• concave mirror or concave lens.

• concave lens or convex lens.

Answer 1

concave mirror or convex lens.

Explanation:

• A concave mirror can produce an enlarged image when the object is placed between the focal point and the mirror. This forms a magnified, virtual image.

• A convex lens can also produce an enlarged image when the object is placed closer to the lens than its focal point. This forms a magnified, virtual image as well.

In contrast:

• A convex mirror always forms a diminished, virtual image.

• A concave lens always produces a diminished, virtual image.

Therefore, the correct options for obtaining an enlarged image are concave mirror and convex lens.
