Draw a line AB and another line PO, angle AOP =10 degree. Place the plane mirror on the line OP, pins P1 & P2. Fix two tall pins P3 and P4to get the reflected ray. Join P4OMeasure angle P1OP4 = y and record the value. Draw line A1B1 such that angle X that angle A1OA = 10 degree. Replace the plane mirror A1B1 and get the new replaced ray and name as P5 & P6 without changing the position of P1 & P2. Record angle Y. Repeat the experiment by taking x = 20, 30, 40, 50 degrees and determine the value of Y
