The view in the figure is from above a plane mirror suspended by a thread connected to the centre of the mirror at point A. A scale is located 0.75m (the distance from point A to point P) to the right of the centre of the mirror, Initially, the plane of the mirror is parallel to the side of the scale; and the angle of incidence of light ray which is directed at the centre of the mirror is 30°. A small torque applied to the thread causes the mirror to turn 11.5° away from its initial position. The reflected ray then intersects the scale at point Q. The distance from point P to point Q on the scale is A 1.00m B. 0.56m 1.02m 0.86m The view in the figure is from above a plane mirror suspended by a thread connected to the centre of the mirror at point A.
