Metal reflects light better than wood. As such if a sniper saw it they could assume where that unit of troops were. If they knew where a given unit was, it was easier to predict where they'd be coming from if they charged the field.
After the war the trenches went away as the land returned to its original uses, but I found a couple of them left that you can visit. One is Vieil Armand in Alsace, and the trenches were mostly carved in stone so they are well preserved. Also, World War 1 trenches in the Meuse have been restored to their original condition so that people can visit them. The German trenches there were built with concrete reinforcements, but the French trenches had filled in over the years and had to be dug out again.
they can hide and see the enemies with periscope
coninental trenches are trenches that go across countries...i think
Trenches are caused by plate movement.
Reserve trenches
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.
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".
No, binoculars and periscopes are different optical devices. Binoculars use two telescopes to provide depth perception and a wider field of view, while a periscope is a device that uses mirrors to allow an observer to see objects that are not in the direct line of sight.
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.
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.
you had to burn it in the trenches
You would use periscopes for spying or looking above a persons head
Periscopes primarily come in two types: the traditional optical periscope and the modern digital or electronic periscope. The traditional periscope uses mirrors or prisms to allow the user to see over obstacles, commonly used in submarines. Digital periscopes incorporate cameras and electronic displays, enabling enhanced image capture and transmission. Additionally, there are specialized periscopes, like those used in military applications or for specific scientific purposes, which may have unique features based on their intended use.
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.
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.
