Simply, a periscope allows the crew of a submarine to see above water for navigational and combat purposes without actually lifting the submarine from underwater and thereby exposing it to danger.
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.
To see over walls and in submarines
To use a periscope, you look through one end while the other end is extended above an obstacle or around a corner to view something that is out of your line of sight. By using the mirrors inside the periscope, you can see images from a different angle without exposing yourself.
A periscope allows one to see around obstacles or over barriers without being seen. This device is crucial in submarines for observing above the waterline while remaining submerged, providing valuable information for navigation and surveillance.
