WHEN LIGHT FALLS ON A SMOOTH OR POLISHED SURFACE, A PART OF THE LIGHT GETS REFLECTED. THIS IS CALLED REFLECTION OF LIGHT.
Suppose a ray of light AO incident on flat smooth surface. The light is reflected along OB. Here, ON is perpendicular to the surface at the point of incidence of light. ON is called normal to surface at the point of incidence. AO is incident ray and OB is reflected ray. THE ANGLE MADE BY INCIDENT RAY (AO )WITH NORMAL (ON )IS CALLED ANGLE OF INCIDENCE AND IS DENOTED BY "i". THE ANGLE MADE BY REFLECTED RAY (OB) WITH NORMAL (ON) IS CALLED ANGLE OF REFLECTION AND IS DENOTED BY "r".
Laws of Reflection.....
1) The angle of incidence is equal to the angle of reflection. That,
<i = <r
2) The incident ray , the normal to the surface at the point of incidence and the reflected ray, all lie in the same plane...
The same laws holds for reflection from all types of reflecting surfaces, plane or curved.
Using laws of reflection we can determine the path of reflected ray by drawing the normal to the point of incidence....
Hope this will help you!!

There are two laws of reflection
1.According to first law of reflection : The incident ray ,the reflected ray and the normal all lie on the same plane. for ex ,there is incident ray AO, the reflected ray OB and the normal ON, all lie on the same plane , as the plane of paper. They are neither coming up out of the paper,nor going down in the paper.
2.According to second law of reflection : The angle of reflection is always equal to the angle of incidence. For ex, if we measure the angle of reflection NOB , then AON as angle of incidence both will equal.....
