Home Depot Kids Workshop Assembled Forward-looking Periscope
In a periscope, light from an object strikes the top mirror at 45° and bounces off at the same angle. This sends light directly down the tube and onto the lower mirror. This mirror also at a 45° angle, reflects light directly to your eye. A periscope is a useful example of the law of reflection at work.
