Working Principle. A periscope works on the Laws of Reflection which states that the light from the object falls on one mirror at a 45o angle from the object and is reflected. This reflectedlight then falls on another mirror and is again reflected until it reaches the human eye

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.
Recent developments in science and technology have incorporated the use of fiber optics in periscopes. Fiber optic periscopes, such as cystoscopes and endoscopes, are used by medical physicians to view the organs of a human body without requiring invasive procedures. The working principle, construction and applications of periscopes are discussed in the sections below.
