CAN YOU PLEASE SHOW THE IMAGE FORMATION OF AN OBJECT WHEN SEEN THROUGH A PERISCOPE?

Hi

A periscope is an instrument for observation from a concealed position. In its simplest form it consists of a tube with mirrors at each end set parallel to each other at a 45-degree angle. This form of periscope, with the addition of two simple lenses, served for observation purposes in the trenches during World War I. Military personnel also use periscopes in some gun turrets and in armored vehicles.

More complex periscopes, using prisms instead of mirrors, and providing magnification, operate on submarines. The overall design of the classical submarine periscope is very simple: two telescopes pointed into each other. If the two telescopes have different individual magnification, the difference between them causes an overall magnification or reduction.

Principle of the periscope. The periscope on the left uses mirrors at location "a" whereas the right uses prisms at "b". The observer is "c".
