A mirror is an optical device that reflects light, allowing us to see images formed by specular reflection.

In physics labs, additionally, mirrors help study reflection laws, image formation, and focal lengths.

The most common type is the plane mirror, which has a flat surface and forms virtual, upright images.

Additionally, curved mirrors include, concave mirrors, which converge light to a focus and can form real or virtual images and convex mirrors, which diverge light and form virtual, diminished images.

Mirrors are used in experiments to understand ray diagrams, mirror formula, and image characteristics like size, position, and nature.
