First of all we take a chart paper or stiff paper. Let the sheet project a little beyond the edge of the table.

Perform activity again. This time use a sheet of stiff paper or a chart paper. Let the sheet project a little beyond the edge of the Table.
Cut the projecting portion of the sheet in the middle. Look at the reflected ray. Make sure that the reflected ray extends to the projected portion of the paper. Bend that part of the projected portion on which the reflected ray falls. Bring the paper back to the original position. When the whole sheet of paper is spread on the table, it represents one plane. The incident ray, the normal at the point of incidence and the reflected ray are all in the plane when you bend the paper you create a plane different from the plane in which the incident ray and the normal lie. They do not see the reflected ray. What does it indicate? It indicates that the incident ray, the normal at the point of incidence and the reflected ray all lie in the same plane. This is another law of reflection.
