What is the function of periscope in submarines?
A periscope lets you look around walls, corners or other obstacles. Submarines have periscopes so that people inside can what is on the surface of the water. A periscope is a useful example of the law of reflection at work.
What are the two uses of Periscope?
Uses Of Periscope It is used in submarines to determine the distance of a torpedo and helps in deciding the right time for the attack. It is used in a nuclear reactor to observe the chemical reactions that are taking place. In military periscopes are used to observe from their hiding position.
What is the function of periscope in a submarine class 8?
The periscope of a submarine helps its crew to locate any object or enemy ship on the surface of the sea.
What is the concept of Periscope?
A periscope is an instrument for observation over, around or through an object, obstacle or condition that prevents direct line-of-sight observation from an observer’s current position. In its simplest form, it consists of an outer case with mirrors at each end set parallel to each other at a 45° angle.

Which lens is used in Periscope?
Only plane mirrors are used for a simple periscope. An expanded view of the object is required for some distance visions, and therefore convex mirrors are helpful. An erect image is produced by a double reversal of the object. Convex mirrors can be used to view objects that are too close to each other.
How many types of periscope are there?
The 13 Types Of Periscope Chatters – A Survival Guide For Scopers! So Periscope comes along and it’s super cool.
What is a periscope Class 8?
A periscope is a long, tubular device through which a person can see objects that are out of the direct line of sight. The periscope makes use of two plane mirrors to see over the top of things. Principle. A periscope works on the reflection of light from two plane mirrors arranged parallel to one another.
What is periscope in simple words?
: a tubular optical instrument containing lenses and mirrors by which an observer obtains an otherwise obstructed field of view.
What kind of image is formed in Periscope?
virtual image
What is improvised periscope?
Ω A periscope is an instrument forobservation from a concealed position. Ω This is commonly used at wars. For thewarriors to look/see their enemies whencoming. Like in tanks, submarines or evenalone.
How many images are seen in a periscope?
So, many images(>3, 3 images are formed for 90 degrees) are formed. Periscope: Periscope is an example wherein mirrors are placed at 45 degrees w.r.t each other. The light from the object is incident on the mirror M1 at an angle of 45 degrees.
What is a periscope and its uses?
A periscope is an optical instrument that uses a system of prisms, lenses or mirrors to reflect images through a tube. Light from a distant object strikes the top mirror and is then reflected at an angle of 90 degrees down the periscope tube. This activity is part of the Optics Educator Guide.
Is the final image formed in a periscope real?
Light is always reflected away from a mirror at the same angle that it hits the mirror. Hence, the image formed in a periscope is reflected, and therefore is not real.
Why is the image in a periscope upright?
Answer: This is because the light rays from the object are reflected by two mirrors. periscope Solutions: The image formed will be equal distance perpendicular to the mirror (follows the 5 characteristics of mirror image).
How long is a periscope?
Periscopes on submarines may be as long as 60 feet (18 m). When a submarine is submerged to a depth that is equal to the length of the periscope tube, it is considered to be at periscope depth.
Which property of plane mirror is used in Periscope Class 10?
law of reflection
Which mirror is used for periscope?
Note: For a simple periscope, only plane mirrors are used. For some distance visions, an enlarged view of the object is required and hence convex mirrors are helpful.
What is 10th plane mirror?
A plane mirror is a mirror with a flat (planar) reflective surface. For light rays striking a plane mirror, the angle of reflection equals the angle of incidence. Plane mirrors are the only type of mirror for which a real object always produces an image that is virtual, erect and of the same size as the object.
Which mirror is used in street light?
convex mirror
