Book Free DemoIn your earlier classes, you have studied different types of curved mirrors, such as parabolic and spherical mirrors.
A spherical mirror's reflecting surface can be curved inwards or outwards.
A concave mirror is a spherical mirror with a reflecting surface that is curved inwards, facing the centre of the sphere. A convex mirror is a spherical mirror with a curved reflecting surface that faces outwards.
You may now realise that the spoon's curved inwards surface can be compared to a concave mirror, while the bulged surface of the spoon can be compared to a convex mirror.
Spherical mirrors:
In the case of curved mirrors, the reflecting surface is a part of the surface of a sphere. Such mirrors whose reflecting surfaces are spherical in nature are called Spherical mirrors.
Spherical mirrors
Concave mirrors:
The reflecting surface is curved inwards in some spherical mirrors; that is, it faces towards the centre of the sphere. They are called Concave mirrors.
Example:
The mirrors used in vehicle headlights, Reflecting telescopes, Torch lights and shaving mirrors
Concave mirrors in vehicle headlights
Convex mirrors:
The reflecting surface is curved outward in some kind of spherical mirror. They are called Convex mirrors.
Example:
The rear side mirror of vehicles, Optical instruments and safety mirrors
The rear side mirror of a car
