How does light reflect through a periscope
WebA simple periscope is just a long tube with a mirror at each end. The mirrors are fitted into each end of the tube at an angle of exactly 45 degrees (45°) so that they face each other. In the periscope, light hits the top mirror at 45° and reflects away at the same angle. The light then bounces down to the bottom mirror.

In your periscope, light hits the top mirror at a 45-degree angle and reflects away at the same angle, which bounces it down to the bottom mirror. That reflected light hits the second mirror at a 45-degree ...
