Type of lens used in periscope?
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.
Which lens is used in periscope?
Periscopes typically use a combination of lenses, including prisms, to help redirect and magnify light entering the periscope. These lenses work together to ensure that the image transmitted through the periscope remains clear and focused for the viewer.
Did periscope use convex or concave mirror?
The basic periscope uses flat mirrors, to bend and offset the optical path. If magnification is required, then the periscope will use convex objective and eyepiece lenses, becoming a refracting telescope with an offset in its optical path.
What type of lenses are used in a periscope?
A periscope is an instrument for observation from a concealed position. In its simplest form it consists of a tube with mirrors at each end set parallel to each other at a 45-degree angle. This form of periscope, with the addition of two simple lenses, served for observation purposes in the trenches during World War I. Military personnel also use periscopes in some gun turrets and in armoured vehicles.Also known as berinscope.More complex periscopes, using prisms instead of mirrors, and providing magnification, operate on submarines. The overall design of the classical submarine periscope is very simple: two telescopes pointed into each other. If the two telescopes have different individual magnification, the difference between them causes an overall magnification or reduction.
How many mirrors are there in a periscope?
A periscope typically contains two mirrors - one at each end of a hollow tube. The first mirror at the top of the periscope reflects the image into the tube, and the second mirror at the bottom of the periscope reflects the image out to the viewer's eye.
What are the parts of the periscope?
The periscope has several parts: the ocular lenses, the mirror or prism, inversion/reversion prisms, relay lenses, another mirror or prism, and objective lenses.

What part of speech is 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.
When was the first periscope discovered?
The first periscope was invented in the early 19th century by a French engineer named Marie Davey. He used it as a way to see over obstacles while remaining hidden.
What are the ocular lenses of a periscope?
Ocular in this context means eyepiece - the piece that is closest to the human eye that is watching.

What is periscope means?
a tubular optical instrument containing lenses and mirrors by which an observer obtains an otherwise obstructed field of view.
What is a periscope used for?
A periscope: An optical instrument that uses a series of prisms, lenses and mirrors to reflect images through a tube. Most often associated with submarines but they can also have other practical uses.A periscope works by using mirrors to bounce light from one mirror to the other. A normal periscope uses two mirrors at 45 degrees angles to the direction you want to see. The light bounces from one to the other and then to your eye. A periscope helps you to see around corners and over walls, they are also used on submarines so that they out and see around things.
How many mirrors are in submarine?
If you mean in the periscope, two.
