Mirror
A mirror is an object that reflects light in such a way that, for incident light in some range of wavelengths, the reflected light preserves many or most of the detailed physical characteristics of the original light.
Types of Mirrors
- Plane Mirror: A flat mirror that reflects light without forming an image.
- Concave Mirror: A mirror with a surface that curves inward. It can form real or virtual images, depending on the object's position relative to the mirror.
- Convex Mirror: A mirror with a surface that curves outward. It forms virtual, upright, and smaller images.
Reflection of Light
When light strikes a mirror, it bounces off at the same angle at which it hit the mirror. This process is called reflection. The angle of incidence is equal to the angle of reflection.
Uses of Mirrors
- Personal Grooming: Mirrors are used for personal grooming, such as applying makeup and styling hair.
- Optical Instruments: Mirrors are used in telescopes, microscopes, and cameras to redirect and focus light.
- Decorative Purposes: Mirrors are used for interior decoration to create a sense of space and enhance the aesthetics of a room.
