periscope is an optical instrument that allows the viewing of objects that are not in direct line of sight. Periscopes have proven to be of great help to submariners to have a view above the surface of water. Periscopes also help in navigation under water.
A simple periscope only requires mirrors, whilst a more complicated periscope makes use of prisms instead of mirrors. The periscopes used in submarines are complex and use tubes 10 meters in length for to achieve a greater range of scope.
