A lamp is twice as far in front of a plane mirror as a personis. Light from the lamp reaches the person via two paths. Itstrikes the mirror at a 36.1° angle of incidence and reflects fromit before reaching the person. The total time for the light totravel this path includes the time to travel to the mirror and thetime to travel from the mirror to the person. The light alsotravels directly to the person without reflecting. Find the ratioof the total travel time along the reflected path to the traveltime along the direct path.
