THE LAW OF REFLECTION(P 32 01)ApparatusGSN 246Adhesive magnetic board1POG 465Ray box, 6V 20 W1POG 461Diaphragm 1 and 2 slits1POG 400.03Optical disc 1POG 110Plane mirror1Connecting lead2KAL 60/5APower supply1Procedure:Put the plane mirror on the optical disk as shown. The ray of light hits the mirror at point F. Point F is the center of the optical disk. The ray of light is reflected back on it self. The direction of this ray is termed the perpendicular.
Move the ray box until The ray hits the mirror at an angle ° . The angle of incidence (the angle between the normal line (N) and the incoming ray). The angle of reflection (the angle between the normal line (N) and the reflected ray r) is seen to be 30° as well.
After experimenting with different angles of incidence and reading off the corresponding angles of reflection it may be found that:the angle of incidence is always of the same magnitude as the angle of reflection .ROTATING...
