A periscope is used to observe the surface from a submarine
Periscope
The instrument used in submarines to observe the surface of water is called a periscope. A periscope consists of a long tube with mirrors at each end, allowing the viewer to see objects above the water's surface while the submarine remains submerged. The periscope's mirrors reflect light from the surface down the tube to the viewer, providing a view of the surroundings without the need to surface the submarine.
A periscope is the instrument used in a submarine to see above the surface of water. It works by using mirrors to reflect light down into the submarine while allowing for observation of the surface without exposing the submarine itself.
A Periscope or Radar
Periscope.
A submarine is a ship that can travel underwater.
The captain of a submarine looks through a periscope, which allows them to see above the water while remaining submerged. This instrument consists of a series of mirrors and lenses that provide a view of the surface and the surrounding environment. By using the periscope, the captain can observe other ships, land features, and potential threats without exposing the submarine. Additionally, modern periscopes often incorporate advanced technology, including cameras and sensors, to enhance visibility and situational awareness.
When the submarine is upto 20 meters from the surface they use a periscope which is simply 2 pieces of glass at 45 degrees to each other. similar to the periscope used to view from a trench by the army.
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.
The instrument commonly used in submarines to see objects at sea level is called a periscope. It allows submariners to view the surface of the water while remaining submerged. The periscope uses a series of lenses and mirrors to provide a clear line of sight above the water while minimizing exposure. Additionally, modern submarines may also utilize cameras and sonar systems for enhanced visibility and detection.
A submarine can surface from underwater in a matter of minutes, typically taking around 1-3 minutes to reach the surface.
