The View in the Figure Is from Above a Plane

question 33

Multiple Choice

The view in the figure is from above a plane mirror suspended by a thread connected to the center of the mirror at point C. A scale is located 0.65 m (the distance from point C to point A) to the right of the center of the mirror. Initially, the plane of the mirror is parallel to the side of the scale; and the angle of incidence of a light ray which is directed at the center of the mirror is 30°. A small torque applied to the thread causes the mirror to turn 12° away from its initial position. The reflected ray then intersects the scale at point B. What is the distance from point A to point B on the scale?

• A)0.37 m
• B)0.58 m
• C)0.76 m
• D)0.89 m
• E)1.0 m
