What is the number of mirrors used to make a simple periscope?

Why are convex mirrors used as side mirrors in cars instead of plane or concave mirrors?
convex mirrors are bent outward,hence can provide the full view of the traffic behind the car and are preferred to concave and plane ones
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.
What is the principle of a periscope?
The answer is that one mirror inside the periscope is meant to reflect the light onto the other mirror so that it goes back into your eyes. It was popularly used in World War I to see over the trenches without being a heavy target to artillery. It is also still used in submarines to see above water level whilst staying submerged.For a diagram that will (should) help, copy and paste the link below:http://www.madsci.org/posts/archives/2000-05/959444445.Eg.1.jpg
When do you use the plane and concave sides of the mirror of a microscope?
Plane Mirror - are standard, flat mirrors, produce images of the same size and distance as the objects they reflect Concave Mirror - Used to focus light, they reflect it inward toward one focal point. Concave mirrors show different types of images, depending on the distance between the mirror and the object reflected. Concave mirrors are used quite frequently in day-to-day life
What types of mirror are used in periscope?
plane mirror

What is a tool made from two mirrors and used to see things that are not in direct line of sight?
A simple periscope is a tool made from two mirrors which can be used to observe objects that are not directly in your line of sight.
What are the uses of a periscope?
Periscopes A periscope is a instrument of observation used for naval use or for other war-like purposes. In fact the first periscope prototype was made by Johann Gutenberg which was used to enable people to see over the heads of the crowd at the Vigintennial religious festival at Aachen. In the navy it is used in submarines to view possible threats such as enemy submarines or sea mines. Marie Davey built the first naval periscope, a simple, fixed periscope using mirrors in 1854. A periscope works by using two mirrors to bounce light from one place to another. A typical periscope uses two mirrors at 45 degree angles to the direction one desires to see. The light bounces from one to the other and then out to the person's eye.
Why do you see the image upside down on a periscope?
If the angles of the mirrors that you used on periscope are not parallel to each other you would see the image upside down.
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.
Which instrument is used in submarines to ovserve the surface of water?
The periscope, basically a vertical tube with mirrors inside it.
How periscope is made?
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.
Why silver is used for making mirrors?
It is responsible for the reflecting action of plane mirrors.-byGitesh Khanna
Why are convex mirrors used as side mirrors in cars instead of plane or concave mirrors?
convex mirrors are bent outward,hence can provide the full view of the traffic behind the car and are preferred to concave and plane ones
What does the prism in the periscope do compared to the mirror usually used?
Mirrors have distortion in the images they project while prisms create undistorted images. :D
Which is correct plane mirror or plain mirror?
A plane mirror is a flat, as opposed to convex or concave, mirror.A plain mirror is just a ordinary mirror as used in a household. These are usually flat mirrors so they are also plane mirrors.Many households have small bathroom mirrors which magnify in this case they would be concave plain mirrors and not concave plane mirrors
