There are generally 2 periscopes, the Primary and the Attack scopes.
The Primary periscope is normally used during normal periscope depth observations of the ocean surface (to verify known Sonar contacts and to search for any not picked up by Sonar) and the sky (aerial targets). In addition to optics, it also contains electronic sensors that receive a multitude of signals, including intelligence and navigation.
The Attack scope is a much smaller profile scope, and as such is much harder to detect during submerged periscope depth approaches or observations. It is only used for final surface target range calculation, or in those instances where extreme stealth is required during periscope operations. It also server as the backup scope (everything on a submarine has at least 1 backup system) should the primary become unavailable. Due to its size, it normally doesn't carry the sensory features of the Primary.

What are periscopes used for?
periscopes are used for submarines and war tanks
Where are periscopes found?
Control room, submarines
What ship uses a periscope?
Big ships such as Navy's have periscopes and submarines have it too. If it is high for you to see you will use an periscopes.
Who uses periscopes?
Periscopes are devices that use mirrors to allow people to view past obstacles. Submarines commonly use periscopes to see above the water without having to surface.
How long do submarines periscopes extend?
The new photonics masts are much different than the older style periscopes, so they only extend about 30 feet (they don't have a hull penetration). For traditional periscopes, usually around 30-40' above the sail/fairwater. Periscope depth for most modern submarines is about 65'.
How are periscopes used in different countries?
i think they are used in submarines,tanks,and also are used like a telescope..
What world war was a periscope used in?
Periscopes were used in both WW1 and WW2. They were used on submarines and in the trenches. It was dangerous to look over the top of a trench so soldiers developed "trench periscopes".
What does a periscope do?
Periscopes were used to watch and observe and spy on the enemy lines during the war and are still used in submarines

How does a crew see the surface of water in a submarine?
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.
What are the two uses of a periscope?
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.
How were periscopes used and how are they used now?
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.
