1) take a white sheet spread it on the table.
2) draw a line M&M' on it and place a plane mirror vertically on this line.
3) take a comb and cover all the opening of it except one. Now let the light pass through the opening such that the parallel light ray fall on the mirror.
4) adjust the set-up in such a way that a pattern of incident and reflected Ray is formed.
5)Now mark point A, B, C, on incident Ray and D, E, F, on the reflected ray.
6) remove the mirror and join the points. Extend the line ABC and DEF to meet MM' at O.
7) OA is incident, OD is reflected ray. Draw ON perpendicular to the MM'.
Therefore we can see that the incident Ray, reflected Ray and the normal all lie in the same plane.
Hope it help you....
