The importance and uses of periscope

The periscopes allow the submarine to search visually for the nearby targets and threats on the surface of the water and in the air when the are submerged at a shallow depth , The periscope is used to monitor the dangerous chemical reactions in the laboratory and they are used in observing the nuclear reactors .

Periscope of submarine

The periscope is an instrument for observation which consists of a tube with mirrors at each set parallel to each other at 45 degree angel and it depends on the occurrence of regular light reflection on the plane mirrors .

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 .

The periscope is used in the submarines to see the events which happening behind a wall or a barrier , and some submarines use complex periscopes which use the prisms instead of mirrors to provide them the magnification .

The periscopes are used to observe over the obstacles of between 9 and 26 metres in height , and they are used in the submarines in general observation of submerged navigation , and for correctly aligning the submarine when firing a torpedo at a target .

The periscope  is used to determine the distance of the torpedo attack , it determines the correct time to fire the torpedo with high speed .

The periscopes are used to observe the dangerous places , they are used in the fuel tanks to see around and above the vehicles .

The periscopes are used in pointing and firing the guns , they are used in  the submarines to view possible threats such as the enemy submarines or the sea mines in the navy .
