The use of the law of reflection to determine a reflected ray is not an easy task. For each incident ray, a normal line at the point of incidence on a curved surface must be drawn and then the law of reflection must be applied. ... The simpler method relies on two rules of reflection for concave mirrors.

THERE ARE 2 LAWS OF REFLECTION
1. INCIDENT RAY , REFLECTED RAY , NORMAL ALL LIE ON THE SAME PLANE
2.ANGLE OF INCIDENT RAY = ANGLE OF REFLECTED RAY(/_i=/_r)
