Solution:
For plane mirror image is of the same length ,for concave mirror image formed is larger than the object n and for convex mirror image is always diminished and erect.The mirror is a plane if the image is vertical, the same size as the object, and does not change in size when the item is moved. The mirror is concave if, when enlarged, the upright image is inverted when the item is moved away from the mirror. The mirror is convex if the image is upright, dims, and stays upright when the item is moved away from the mirror.
