1. According to the first law of reflection The
incident ray, the reflected ray, and the normal (at the
point of incidence), all lie in the same plane. In
Figure 2, the incident ray AO, the reflected ray OB and
the normal ON, all lie in the same plane, the plane of

nor going down into the paper.
2. According to the second law of reflection : The
angle of reflection is always equal to the angle of
incidence. If the angle of incidence is i and the angle of
reflection is r, then :
Zi=2r
? if we measure the angle of reflection NOB, we will find that
