How do mirrors work?
Mirrors work by reflecting light waves back to the source. This can be done by using a convex mirror, a concave mirror, or a plane mirror.
Convex mirrors
Convex mirrors are curved outward from the center. This causes the light rays to converge (meet) at a point behind the mirror. The focal point of a convex mirror is located at the center of the mirror.
Concave mirrors
Concave mirrors are curved inward from the center. This causes the light rays to diverge (spread out) as they approach the mirror. The focal point of a concave mirror is located at a point in front of the mirror.
Plane mirrors
Plane mirrors are flat and parallel to the ground. Light rays that hit a plane mirror will reflect perfectly back in the same direction they came from.
The focal length of a mirror is the distance from the mirror's focal point to the center of the mirror. The focal length of a mirror is determined by its curvature and the material of the mirror.
Mirrors are used in a variety of applications, including:
- Rear-view mirrors in cars
- Security mirrors in buildings
- Contact lenses
- Makeup mirrors
Mirrors are a fascinating and versatile optical device that can be used to create a variety of images and effects.
