why convex mirror is used in rear view mirrors and not concave mirrors

by Vesta Blick II Published 3 years ago Updated 2 years ago

Convex mirrors are used in car rear view mirrors as they form a smaller image of the object. Convex mirror can therefore be used to view a much larger area than it would be possible with concave mirror. Concave mirror on the other hand forms magnified and inverted image of the object.

A convex mirror is preferred as a rear-view mirror in cars and vehicles as it gives a wider field of view, that helps the driver to see most of the traffic behind him. Convex mirrors always form an erect, virtual, and diminished image of the objects placed in front of it.Feb 28, 2021

Why are convex mirrors called diverging mirrors?

Convex mirrors are known as diverging mirrors because when light reflects off of them, the rays move in opposite directions. In contrast concave mirrors, which curve inward, cause reflected rays to converge after reflection. Another unique aspect of convex mirrors is that they create virtual images. When the light rays are reflected, they can be ...

How do convex mirrors work?
