6. Regular Reflection
• It is when parallel rays of light fall
on a smooth surface and reflect
parallel also.
7. Diffuse Reflection
• It is when parallel rays of light fall
on a rough surface and reflect in
different directions.
8. As you saw, when we draw the normal
and then place the incident and
reflected rays of light of its sides,
the angle between the incident light
and normal line and the angle
between reflected light and normal
line should be the same.
10. Angle of Incidence
• Angle of Incidence is the angle
between the incident ray and normal.
Angle of
Incidence
11. Angle of Reflection
• Angle of Reflection is the angle
between the reflected ray and
normal.

Reflection
12. Point of Incidence
• Point of Incidence is the point at
which the normal, reflected ray and
incident ray meet on a plane surface.
Point of Incidence
13. Laws of Reflection
1. The incident ray, reflected ray and
normal at the point of incidence lie on the
same plane.
2. The angle of incidence and the angle of
reflection is the same when measured.
