Answer 1

Answer:

Explanation:

first of all all you have to do is take the materials required. Once you understand what the materials are, continue reading.

understand the experiment by looking at the diagram. Take a drawing board(stiff board) and place paper and mirror as shown.mark ray P as shown with some suitable angle to normal ON . now look in the mirror in such  way that you find the reflection of the ray p in it. by looking at the mirror, draw the straight line (as if it is coming out of mirror) such a way that ray p and the newly formed ray are equal in angle with the normal that lies between them.The experiment shows the laws of reflection:1. the incident ray and reflected ray lie on opposite sides of normal. (ray p is incident ray and ray O is reflectd ray from diagram2) 2.the incident ray, reflected ray and normal lie on the same plane( i.e. they are drawn on a planar surface 2D) 3.the angle of incidence is equal to angle of reflection.
