उत्तर
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.
