If the angle of incidence were not equal to the angle of reflection, the distance traveled by a light ray going on a path composed of two straight-line segments intersecting at the reflecting surface would be: A. Less than it is for the actual path. B. Greater than it is for the actual path. C. The same as the actual path. D. Any on the above answers may be valid, depending on further geometric details.
