Visible waves, ie, visible light is piped through a periscope.
A concave lens in a periscope is used to invert the image received from the object being observed. This type of lens helps to create a larger field of view within the periscope by expanding the image. The concave lens also helps to focus the incoming light rays onto the mirror system of the periscope for reflection.
Simon Lake is attributed with the invention of the Periscope in 1902. However, Sir Howard Grub is known for perfecting this design.
A periscope typically uses a system of lenses and mirrors to allow people to view objects from a concealed position. The primary lenses used in a periscope are usually simple lenses or lens systems that help to gather and focus light from the outside environment into the periscope tube for viewing.
A Periscope is a type of observation material used during World War I. It is made up of two mirrors in parallel position with an angle of 45 degree placed inside a case. Periscope can also be seen on submarines and other military equipment.
An early form of the periscope was used to see over the tops of the trenches.
well there really is no antonym that i know of for periscope because a periscope is an object.
You tell me
The captain of the submarine raised the periscope to see if there's danger.
In trench warfare much use was made of devices which allowed an observer to safely see across no-mans land. The periscope was one such item.The periscope was made of wood and folded into halves so as to allow ease of carriage. When used in the trenches the folding periscope was often camouflaged with sacking. A periscope is also used for looking out of boats to see if an enemy ship is around.

A periscope typically uses a set of two plane mirrors to reflect and redirect light at a 90-degree angle, allowing the viewer to see around obstacles or over barriers. The mirrors used in a periscope are flat and aligned at specific angles to ensure proper reflection and image visibility.
The word "periscope" is a noun. It refers to a device used for seeing over obstacles or around corners, typically by the use of mirrors and lenses.
