A Periscope is a type of observation material used during World War I. It is made up of two mirrors in parallel position with an angle of 45 degree placed inside a case. Periscope can also be seen on submarines and other military equipment.
The biggest periscope ever made was built in 2014 by experts at Purdue University. It was an experimental periscope that measured 4.7 meters (15.4 feet) in length. It was designed for use in a digital imaging laboratory.
The cost of a periscope can vary depending on the size, quality, and brand. On average, a simple periscope for recreational use can range from $20 to $100. More specialized or military-grade periscopes can cost several thousand dollars.
The periscope of a submarine is located in the sail, also known as the conning tower. This structure is situated above the main hull and contains various equipment, including the periscope, which allows submariners to observe the surface while the submarine remains submerged.
Light enters the periscope through one end and reflects off a series of mirrors inside which are set at specific angles. The mirrors then redirect the light so that it exits through the other end of the periscope, allowing the viewer to see objects or scenes that are not in a direct line of sight.

it is prism
The periscope was invented in the year 1854 by French inventor Hippolyte Marié-Davy.
In trench warfare much use was made of devices which allowed an observer to safely see across no-mans land. The periscope was one such item.The periscope was made of wood and folded into halves so as to allow ease of carriage. When used in the trenches the folding periscope was often camouflaged with sacking. A periscope is also used for looking out of boats to see if an enemy ship is around.

in 1999 SIMON LAKE invented it and SIR HOWARD GRABB perfected it
