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 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.
What are different types of periscope?
There are two main types of periscopes: optical periscopes, which use mirrors to reflect light and provide a view of objects above the surface of the water, and digital periscopes, which use cameras and screens to provide a similar view. Optical periscopes are commonly used in submarines, while digital periscopes are becoming more popular due to advances in technology.
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'.
Who uses periscopes?
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.
What are periscopes used for?
Periscopes are used to allow someone to see over or around obstacles such as walls, fences, or the surface of water. They use mirrors to reflect light and provide a view from a higher vantage point without being directly in line of sight. They are commonly used in submarines, armored vehicles, and some sporting events.
How are periscopes used in different countries?
i think they are used in submarines,tanks,and also are used like a telescope..
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.
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
What does a periscope does?

How do nuclear reactors use periscopes?
Nuclear reactors do not typically use periscopes. Periscopes are usually used in submarines to see above water while remaining submerged. Nuclear reactors utilize control rooms with monitoring equipment and cameras to observe and control the reactor's operations.
