A lamp is twice as far in front of a plane mirror as a person
is. Light from the lamp reaches the person via two paths. It
strikes the mirror at a 38.3° angle of incidence and reflects
from it before reaching the person. The total time for the light to
travel this path includes the time to travel to the mirror and the
time to travel from the mirror to the person. The light also
travels directly to the person without reflecting. Find the ratio
of the total travel time along the reflected path to the travel
time along the direct path.
