To see over walls and in submarines
The concept of a periscope dates back to the ancient Greek mathematician Hero of Alexandria around 300 BC. The modern periscope was developed in the 19th century and has been used extensively in submarines for naval operations since the early 1900s. Today, periscopes are also used in various other applications, such as in armored vehicles and in some sports like rowing.
A periscope is the instrument used in a submarine to see above the surface of water. It works by using mirrors to reflect light down into the submarine while allowing for observation of the surface without exposing the submarine itself.
The cost of a periscope can vary depending on the size, quality, and brand. On average, a simple periscope for recreational use can range from $20 to $100. More specialized or military-grade periscopes can cost several thousand dollars.
Simply, a periscope allows the crew of a submarine to see above water for navigational and combat purposes without actually lifting the submarine from underwater and thereby exposing it to danger.
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.
If the angles of the mirrors that you used on periscope are not parallel to each other you would see the image upside down.
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.

Visible waves, ie, visible light is piped through a periscope.
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.
The Captain used the periscope to locate the enemy ships.A periscope is the eye of a submarine.
Yes sonar can be used at periscope depth. Surface ships also have sonar arrays on them. They are usually used to detect submarines.
