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.
No - most military submarines are limited to crush depths above 2,000 feet.
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.
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.

well i can tell you what it is but im not quit sure what you mean by an example.... it is a optical instrument for viewing objects that are above the level of direct sight; mostly used in submarines

Frogs live both underwater and above (on land). They are amphibians.
Traditionally, by using a periscope to view optically above the surface. As periscopes are a weak point in a submarine - modern nuclear submarines use external cameras instead of periscopes.
Island arc volcanoes are islands that form in chains underwater and emerge above the surface for form a series of islands.
