When I looked at a mirror, I found that my size and my image's size is the same. What could be the type of mirror that I am looking at?
Plane
Concave
The image formed by a plane mirror is always erect and of the same size as the object.
Also, if a person stands at the centre of curvature of a concave mirror then even in this case the image will be of the same size as the object but in the case of convex mirror the image formed is always diminished.
Hence the mirror could be a concave or a plane mirror.
