Answer 2

law of reflection :-

B-)The incident, reflected and the normal lie in the same plane

B-)angle of incidence is equal to the angle of reflection

so there are 3 types of mirror
plane mirror: it from the virtual inside the mirror and it is equal to the both incident and reflected

concave :form the real image when kept in respective length from the mirror

convex mirror :forms virtual image at the respective distance from the mirror
