उत्तर
We can identify convex mirror, concave mirror, and a plane mirror by looking at them one by one.
- If the size of the image of an object is of the same size as that of the object, then that mirror is a plane mirror.
- If the size of image of an object increases as the object is brought closer to the mirror and the size of the image of the object decreases when the object is taken away from the mirror, then that mirror is a concave mirror.
- If the size of the image of an object remains diminished, either the object is moved away from the mirror or moved towards the mirror, then that mirror is a convex mirror.
