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. WebFrom now on we can conclude that a periscope is an instrument that uses a system of prisms, lenses or mirrors to reflect images through a cylindrical tube. Light from a distant object hits the upper mirror and is then reflected at a 90-degree angle through the cylindrical tube of the periscope.
