What is a convex and concave mirror?
Concave mirror- A concave mirror is a mirror that is curved inward in the middle.
It is also known as converging mirrors, due to the fact that when parallel incident rays fall on the surface of the mirror, the rays will reflect and meet at a particular point and form the real or virtual image, depending on the position of the object.
The focal point of the concave mirror lies in front of the mirror.
It is used in torches and vehicle headlights.
Convex mirror- A convex mirror is a mirror that is curved outward in the middle.
It is also known as diverging mirror, as the incident ray emerging from the same source (point), will reflect off and move in a different direction. Consequently, the light rays will not intersect on the object side of the mirror and form the virtual image of the real object.
The focal point of the convex mirror lies behind the mirror.
It is used as rear-view mirrors in vehicles, to enable the driver to see the traffic behind him.
