Answer 1

Hint: A mirror having a curved reflecting surface is known as a curved mirror. The surface might be convex (bulging outward) or concave (bulging inward) (recessed inward). The surfaces of most curved mirrors are formed like a portion of a sphere, although different forms are occasionally employed in optical equipment. Because spherical mirror systems, like spherical lenses, suffer from spherical aberration, the most popular non-spherical form is parabolic reflectors, which are used in optical equipment such as reflecting telescopes that require to picture distant objects.

Complete answer:
A convex mirror, also known as a diverging mirror, is a curved mirror with a reflecting surface that bulges toward the light source. Because convex mirrors reflect light outwards, they are not utilised to concentrate light. Because the focal point (F) and the centre of curvature (2F) are both fictitious places "within" the mirror that cannot be reached, such mirrors always produce a virtual picture.

As a result, because the picture generated by these mirrors is inside the mirror, it cannot be projected on a screen. The picture is smaller than the item at first, but as the object moves closer to the mirror, it grows larger.

The reflecting surface of a concave mirror, also known as a converging mirror, is sunken inward (away from the incident light). Light is reflected inward by concave mirrors to a single focus point. They're used to concentrate light. Concave mirrors, unlike convex mirrors, produce a variety of images based on the distance between the item and the mirror.

Because they tend to gather light that falls on them, redirecting parallel incoming rays toward a focus, these mirrors are referred to as "converging mirrors." Because the normal to the mirror surface varies at different locations on the mirror, light is reflected at varying angles at different spots.

Hence
Concave mirror:
• In solar concentration.
• Makeup mirror.
• Shaving mirror.
Convex mirror:
• In rearview mirrors of vehicles.
• In Searchlights.
Plane mirror:
• In periscopes.
• To see the face.

Note:Convex mirrors are employed as a simple and useful security feature in certain automated teller machines, allowing consumers to see what is going on behind them. Similar devices are available for use with standard computer displays. Convex mirrors make things appear smaller while providing a greater observation area. Concave mirrors are used in lighting applications to collect light from a tiny source and guide it outward in a beam, such as torches, headlights, and spotlights, or to collect light from a broad area and focus it into a small point, such as concentrated solar power. Optical cavities, which are crucial in laser building, are formed using concave mirrors.
