state three differences between a convex and a concave mirror.


Concave Mirror Convex Mirror
It is made by silvering a part of the outer surface of hollow sphere, so the reflection takes place from the inner side of the hollow surface. It is made by silvering a part of the inner surface of hollow sphere, so the reflection takes place from the bulging surface.
It converges the light rays incident on it after reflection. It diverges the light rays incident on it after reflection
The image formed by it is real as well as virtual. For all positions of object at or beyond focus, the image is real, while for the position of the object between focus and pole, the image is virtual. The image formed by it is always virtual for all positions of object in front of it.
The image can be magnified, of same size or diminished, depending upon the position of the object. For object away from centre of curvature, the image is diminished, for object at centre of curvature, the image is of same size and for object before centre of curvature, the image is magnified. The image is always diminished for all positions of the object infront if it.
