A curved mirror is a mirror with a curved reflecting surface. The surface may be either convex (bulging outward) or concave (recessed inward).
Convex mirrors-
A convex mirror or diverging mirror is a curved mirror in which the reflective surface bulges towards the light source.Convex mirrors reflect light outwards, therefore they are not used to focus light.
As a result, images formed by these mirrors cannot be projected on a screen, since the image is inside the mirror.
Characteristics of Convex Mirrors-
- A convex mirror is also known as a diverging mirror as this mirror diverges light when they strike on its reflecting surface.
- A convex mirror is also known as a diverging mirror as this mirror diverges light when they strike on its reflecting surface.Virtual, erect, and diminished images are always formed with convex mirrors, irrespective of the distance between the object and the mirror.
Uses of Convex Mirrors-
- Inside buildings. You might have noticed that large office buildings, stores, hospitals, and other many other buildings have convex mirrors in the corners.
- Sunglasses
Concave mirrors-
A concave mirror, or converging mirror, has a reflecting surface that is recessed inward (away from the incident light). Concave mirrors reflect light inward to one focal point. They are used to focus light.
Characteristics of concave mirrors-
Concave mirrors can produce both real and virtual images; they can be upright (if virtual) or inverted (if real); they can be behind the mirror (if virtual) or in front of the mirror (if real); they can also be enlarged, reduced, or the same size as object.
Uses of Concave mirrors-
- Shaving mirrors.
- Head mirrors.
- Ophthalmoscope.
- Astronomical telescopes.
