difference between convex and concave mirror ?
Answers
While,
Concave mirror is a shpreical mirror in which the reflecting surface and the centre of curvature lies on the same side of the mirror.
Convex mirror is also called diversing mirror
While,
Concave mirror is also called converging mirror.
Concave mirrors are used in telescopes, solar cookers, etc.
While,
Convex mirror aare used in spoons, car side mirrors, etc.
Hope this may help uh!!!!
Concave mirror :-
If a hollow sphere is cut into parts and the outer surface of the cut part is painted. Then it becomes a mirror with its inner surface as the reflecting surface This kind of mirror is known as a concave mirror. Light converges at a point when it strikes and reflects back from the reflecting surface of the concave mirror. Hence, it is also known as a converging mirror. When the concave mirror is placed very close to the object, a magnified and virtual image is obtained. But if we increase the distance between the object and the mirror then the size of the image reduces and a real image is formed. So the image formed by the concave mirror can be small or large and it can also be real or virtual.
Convex mirror:-
If the other cut part of the hollow sphere is painted from inside, then its outer surface becomes the reflecting surface. This kind of mirror is known as convex mirror. 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. Apart from other applications, the convex mirror is mostly used as a rearview mirror in vehicles
