You would use periscopes for spying or looking above a persons head
No, periscopes allow you to observe objects while you are hidden.
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.
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.
It could be said that submarine crews use periscopes, and that is probably the most common use of these devices.

People use periscopes primarily on submarines to see above the water's surface without the vessel being detected. Periscopes are also used in some sports events, like in golf to see over crowds or obstacles. Additionally, periscopes are sometimes used in buildings or construction sites to view areas that are difficult to access.

Periscopes look like long tubes that have lens at both ends and have handles that can move it so other people can look through it
Spies use periscopes to discreetly observe or gather information without revealing their presence. Periscopes allow them to see over walls, around corners, or from hidden locations, making it easier to surveil a target without being detected.
