A beam of light strikes one mirror of a right angle mirror assembly at an angle of incidence $4 5^{\circ}$ as shown in the figure. The right angle mirror assembly is rotated such that the angle of incidence becomes 60°. Which of the following statement is correct about the emerging light beam.

Question

TestHub · Accepted Answer

Two perpendicular mirrors turn the ray by exactly 180° for any angle of incidence.

The emerging beam is always antiparallel to the incident beam.

The incident beam has not changed, so the emerging beam is parallel to the original emerging beam.
