Answer 1

Explanation:

A curved mirror is a mirror with a curved reflecting surface. The surface may be either convex (bulging outward) or concave (recessed inward). Most curved mirrors have surfaces that are shaped like part of a sphere, but other shapes are sometimes used in optical devices. The most common non-spherical type are parabolic reflectors, found in optical devices such as reflecting telescopes that need to image distant objects, since spherical mirror systems, like spherical lenses, suffer from spherical aberration. Distorting mirrors are used for entertainment. They have convex and concave regions that produce deliberately distorted images. They also provide highly magnified or highly diminished (smaller) images when the object is placed at certain distances.

Answer 2

$\bold{Concave \: Mirror}\colon -$A spherical mirror which has the inside surface as the reflecting surface.

• It is curved inwards.
• The inside surface is the reflecting surface.

$\bold{Convex \: Mirror}\colon -$A spherical mirror which has the outside surface as the reflecting surface.

• It is curved outwards.
• The outside surface is the reflecting surface.

Uses of Concave Mirror :-

• Used as shaving mirror or make-up mirror for close look.
• Used by dentist for examining the teeth.
• Used in solar cooke, so that they can concentrate the rays of the sun at one point.
• Used as reflectors in torch and headlights of vehicles to produce high intensity beam.

Uses of Convex Mirror :-

• It is used as a rear view mirror in cars to have a wide view of the traffic coming from behind.
• In supermarkets to look out thieves and shoplifters.
• Convex mirrors are widely used for making magnifying glasses.
• Convex mirrors are also used for security purposes in various places.
