Submarines typically use periscopes to see above water while remaining submerged. A periscope consists of a long tube with mirrors or prisms that allow the crew to view the surface from a safe depth. Modern submarines may also utilize advanced optical systems and sensors, including cameras and radar, to enhance visibility above water. These technologies enable submarines to gather crucial information without exposing themselves to potential threats.
When you look into a periscope, you see a magnified view of what is above the surface of the water. Periscopes are commonly used on submarines to enable viewing above the waterline without the vessel having to surface.
Periscopes are mainly used by submarines and armored vehicles to allow those inside to see above the water or around obstacles without having to expose themselves. They can also be used in various types of research instruments and some optical devices.
They were used in the first world war in submarines. The are used now also for submarines and also war tanks. The outer coating of the periscope for the submarines were firm and waterproof for protection from the water pressure. As for the war tank the periscope is able to turn 360 degrees.
A periscope allows people to see above obstacles or around corners without being detected. It was commonly used on submarines to see above water while the submarine remained submerged. This helped to gather information about the surroundings and potential threats.
There are many more than just two uses of a periscope. In WW1 periscopes were used to look over the trenches and across no mans land at the enemy. Of course periscopes are used in submarines to see above the water. There are also many other uses but if you are just looking for two main uses then they would be looking over walls and around corners.
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.
they use a light built into their models.
To see over walls and in submarines
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.

Periscope
Periscopes are optical devices that allow you to look at objects that are not in the straight line of vision. It usually consists of a metal tube with mirrors within it usually tilted 45 degrees as shown below. Thus the object around a corner can be viewed. Used mostly in submarines. It allows sailors submerged under water to see and monitor what is happening above water. See any World War II movie with submarines or Walt Disney’s “Twenty Thousand Leagues Under The Sea” and you can see a periscope in action.
