If one places a perpendicular mirror at the end of a laser beam passing through several materials at different angles, what happens?
Answer a. At refraction points it bends the other way and leaves the path.
b. The light retraces its path exactly in reverse.
c. At reflection points it bends the other way and leaves the path.
d. It depends on the path
Expert's answer
