Answers
Answer:
Characteristics of the image formed by a plane mirror :
It is virtual
It is erect and of the same size as the object
The distance of the object from the plane mirror is the same as the distance of the image from the plane mirror.
One of the important characteristics of the image is that it is laterally inverted. It means if you raise your left hand it would appear in the plane mirror that you have raised your right hand.
Laws of Reflection
There are two laws of reflection and they are:
The angle of incidence and the angle of reflection are always equal.
The incident ray, the normal at the point, and the reflected ray, all lie on the same plane.
