PERISCOPES Meaning and
Definition
-
Periscopes are optical instruments designed to provide a view of objects that are above or below the line of sight. They consist of a long, narrow tube with mirrors or prisms placed at opposite ends to reflect and redirect light. The word "periscope" is derived from the Greek words "peri" meaning "around" and "skopein" meaning "to look or see."
Periscopes are commonly used in military submarines to enable the crew to view the surface while the submarine remains submerged. The periscope allows a periscope mast (also known as a "conning tower") to extend above the water, providing a clear view of the surroundings without revealing the submarine's position. This is achieved by the mirrors or prisms inside the periscope, which reflect the light from the surface and redirect it to the viewer's eyes.
Additionally, periscopes are also utilized in various other applications, such as armored vehicles, tanks, and observation towers, allowing individuals to observe their surroundings without exposing themselves to potential danger. In some cases, periscopes may also be found in scientific instruments for geological or biological research.
Overall, periscopes are invaluable tools that enable individuals to obtain visual information from positions that would otherwise be inaccessible or hazardous.
