|Concave mirror||Convex mirror|
|What are convex and concave mirrors?||If the inner side of the spherical mirror is reflecting, it is called a concave mirror.||If the outer side of the spherical mirror is reflecting, it is called a convex mirror.|
|Image||Concave mirrors can form inverted and real images and also virtual and erect images.||Convex mirrors form virtual and erect images|
|Size||Size can be smaller, larger or of the same size depending on the position of the object.||Smaller than the size of the object, always.|
|Position||Depends on the position of the object.||Always within the focus, irrespective of the position of the object.|
The convex mirror is used as a side-view/rear – view mirror of a vehicle because it forms an erect and smaller image. Convex mirror gives a wide rear view.
The concave mirror is a converging mirror, so it is used for many purposes.
