Periscope Invented by

Jules Carpentier

==>>A periscope is defined as an instrument used for observing over, around or through an obstacle or object which is prevented by direct line of sight.

==>>It consists of an outer case with mirrors at each end at 45° angle. These mirrors are placed parallel to the surface.

==>>The periscope is used in the submarines to see what is going on the water surface.

==>>It was used for observation purposes in the trenches during World War I, It is used in some gun turrets and it is used in armed vehicles.

==>>In 1854, Hippolyte Marié-Davy invented the first naval periscope, consisting of a vertical tube with two small mirrors fixed at each end at 45°. Simon Lake used periscopes in his submarines in 1902.
