A mirror is a smooth, highly reflective surface that reflects light and creates an image of whatever is in front of it. Mirrors are commonly used for personal grooming, decoration, and in optical instruments such as telescopes and microscopes.

A mirror is a reflective surface, typically made of glass coated with a metal film, that reflects light and creates an image of the object placed in front of it. Here are some characteristics and functions of a mirror:
Types of Mirrors
Mirrors are primarily classified into three types based on their shape and curvature:
- Plane mirror: A flat, non-curved surface that reflects light at the same angle at which it strikes.
- Concave mirror: Has a curved surface that bulges inward, like the interior of a bowl. It converges light rays that strike it.
- Convex mirror: Has a curved surface that bulges outward, like the exterior of a bowl. It diverges light rays that strike it.
Reflection of Light
- Mirrors reflect light based on the laws of reflection. The incident ray (light ray striking the mirror) and the reflected ray (light ray bouncing off the mirror) make equal angles with the normal (line perpendicular to the surface) at the point of incidence.
- The angle of incidence and the angle of reflection are equal.
Image Formation
- Plane mirror: Forms a virtual, upright, and congruent image that is the same size and distance behind the mirror as the object is in front of it.
- Concave mirror: Can form either virtual or real images, depending on the object's position relative to the mirror's focal point.
- Convex mirror: Always forms a virtual, upright, and diminished image, smaller than the object.
Uses of Mirrors
- Reflection: Mirrors are used to see our reflections, adjust makeup, or check our appearance.
- Decoration: Mirrors can add depth and brightness to a room, making it appear larger.
- Optical devices: Mirrors are essential components in telescopes, microscopes, and other optical devices.
- Medical and dental applications: Mirrors are used for examining the inside of the body, such as for dental checkups or throat exams.
- Security and surveillance: Mirrors are used in security cameras and surveillance systems to provide a wider field of view.
- Traffic control: Convex mirrors are placed at intersections and curves to help drivers see around blind spots.
- Automotive: Mirrors are used in cars and other vehicles as rearview mirrors and side mirrors for visibility.
Mirrors are widely used in various applications due to their ability to reflect light and create images.
