POLARIZATION OF EM WAVE MEANS DIRECTION OF ELECTRIC FIELD IN WAVE--
INTENSITY IS DIRECTLY proportional TO SEQURE OF ELECTRIC FIELD VECTOR
WHEN FIRST POLAROID IS ROTATED BY AN ANGLE (A) ELECTRIC FIELD THAT PASS THROUGH POLAROID CONTAIN ONLY A SINGLE COMPONENT OF IT . SO INTENSITY BECOME
I1 = I0 COS2A
SIMILARY WE CAN SOLVE FOR SECOND POLAROID
