In a periscope, plane mirrors are set at 45-degree angles to reflect light twice. The first mirror reflects the light from the object being viewed down the periscope, and the second mirror reflects the light towards the observer's eye, allowing them to see around obstacles. This arrangement creates an angled path for light to travel, enabling the viewer to see objects that are not in their direct line of sight.

What is the number of mirrors used to make a simple periscope?
A simple periscope typically uses two mirrors arranged at a 45-degree angle to each other. This allows light to be reflected through the periscope, allowing the viewer to see objects around corners or over obstacles.
Which type of mirror in Periscope?
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.
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.
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.
How are plane mirrors used?
Plane mirrors are used to reflect light. They are commonly found in bathrooms, dressing tables, and on vehicles as side mirrors. They are also used in optical instruments like periscopes and kaleidoscopes.

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.
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.
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.
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.
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.
Which instrument is used in submarines to ovserve the surface of water?
The instrument used in submarines to observe the surface of water is called a periscope. A periscope consists of a long tube with mirrors at each end, allowing the viewer to see objects above the water's surface while the submarine remains submerged. The periscope's mirrors reflect light from the surface down the tube to the viewer, providing a view of the surroundings without the need to surface the submarine.
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.
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.
How are plane mirrors used?
Plane mirrors are used to reflect light. They are commonly found in bathrooms, dressing tables, and on vehicles as side mirrors. They are also used in optical instruments like periscopes and kaleidoscopes.
