Information about periscope

Answers

Answered by narendra6156

A periscope is an optical instrument that allows objects that are not in direct line of sight to be viewed. Periscopes have proven to be of great help to submariners by allowing these professions to have a view above the surface of water and aid in navigation under water. A simple periscope only requires mirrors, whereas a more complicated periscope utilizes prisms rather than mirrors. The periscopes used in submarine applications are complex, typically requiring the use of tubes that are at least 10 meters in length to achieve a greater range of scope.
