The Law of “REFLECTION” The Law of Reflection states that- " the angle of incidence (incoming ray) equals the angle of reflection (outgoing ray)" The law works for FLAT, PLANE surfaces only. The angles are measured from a perpendicular line to the surface called a NORMAL. NORMAL
Plane Mirror Suppose we had a flat , plane mirror mounted vertically. A candle is placed 10 cm in front of the mirror. WHERE IS THE IMAGE OF THE CANDLE LOCATED? mirror Object Distance, D o = 10 cm Same side as the object? On the surface of the mirror? Behind the mirror?
