Name a mirror that can give an erect and enlarged image of an object.

Variety of Reflective Surfaces: In the realm of optics, mirrors are categorized based on their shapes and the types of images they produce. The two primary types are concave and convex mirrors, each with distinct image-forming characteristics.

Unique Properties: A concave mirror is a spherical mirror that curves inward, resembling a portion of the interior of a sphere. This type of mirror is known for its ability to focus light and produce various types of images depending on the object’s position relative to the mirror.

Erect and Enlarged Images: When an object is placed between the focal point (F) and the pole (P) of a concave mirror, the mirror produces a virtual, erect, and enlarged image of the object. This is unlike the diminished, real, and inverted images formed when the object is placed beyond the focal point.

Practical Use: This property of concave mirrors is utilized in everyday objects like shaving mirrors or makeup mirrors. These mirrors provide an enlarged and erect image, allowing for detailed viewing, which is essential for precise grooming tasks.

Contrasting Characteristics: In contrast, a convex mirror, which curves outward, cannot produce an enlarged and erect image. Convex mirrors always form images that are virtual, erect, but diminished, making them unsuitable for applications where magnification is required.

Optimal Choice for Enlargement: Therefore, for obtaining an erect and enlarged image of an object, a concave mirror is the optimal choice. Its unique ability to magnify while maintaining the orientation of the image makes it indispensable in specific applications requiring detailed and enlarged views.
