Prisms and lenses are used in some periscopes instead of mirrors to achieve specific optical effects and improve image quality. Prisms can bend light without the need for reflection, allowing for a more compact design and reducing image distortion. Additionally, lenses can focus and correct light paths, enhancing clarity and brightness. Using prisms and lenses can also simplify construction and alignment compared to mirrors, making the periscope more efficient.

What are facts about periscopes?
Periscopes are optical devices that allow users to see objects or views that are not directly in their line of sight. They are commonly used on submarines to observe above-water surroundings without surfacing. Periscopes work by using mirrors to reflect light, enabling users to view images from a different angle.
What object did Isaac newton use to study light?
A telescope lenses and prisms
How are periscopes built?
We made some in class using mirors and a cardboard box. You have to cut two small holes on opposite sides of the box. Then on the opposite side position the mirrors on opposite sides of the box. (on the thinner side) then stick them in the right position and your done. To position mirrors: Make sure you can see out of the top from the the bottom mirror!
Why do telescope images look upside down?
Telescope images appear upside down primarily due to the way light is focused through lenses or mirrors. When light rays enter the telescope, they converge to form an image, but because of the laws of optics, the image is inverted. This effect can be corrected using additional optical components, such as prisms, but many telescopes, especially simpler ones, display the inverted image as a standard feature.
Principle of light of a periscope use to work?
The principle behind a periscope is the reflection of light at two or more angles using mirrors to allow an observer to see objects that are not in their direct line of sight. The light enters one end of the periscope, reflects off the mirrors inside, and exits the other end, allowing the observer to see around obstacles or over barriers. This principle is based on the law of reflection, where the angle of incidence is equal to the angle of reflection.
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 do optical components contain?
Main products are Optical Windows, Mirrors, Prisms, Lenses, waveplates and Color Filters,
What are facts about periscopes?
Periscopes are optical devices that allow users to see objects or views that are not directly in their line of sight. They are commonly used on submarines to observe above-water surroundings without surfacing. Periscopes work by using mirrors to reflect light, enabling users to view images from a different angle.
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.
What are the types of periscopes?
Periscopes primarily come in two types: the traditional optical periscope and the modern digital or electronic periscope. The traditional periscope uses mirrors or prisms to allow the user to see over obstacles, commonly used in submarines. Digital periscopes incorporate cameras and electronic displays, enabling enhanced image capture and transmission. Additionally, there are specialized periscopes, like those used in military applications or for specific scientific purposes, which may have unique features based on their intended use.
What is prismatic periscope?
A prismatic periscope is an optical device that uses prisms to reflect light and enable users to see objects that are not in their direct line of sight. Unlike traditional periscopes, which typically use mirrors, prismatic periscopes utilize total internal reflection in prisms to achieve a more compact design and improved image quality. They are commonly used in submarines, for surveying, and in various optical instruments. This design allows for a more efficient transfer of light and can provide a clearer image.
What is a periscope in detail?
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. At the bottom of the periscope, the light strikes another mirror and is then reflected into the viewer's eye.
What is totally reflecting prisms?
the defects of mirrors are overcome if 45 degree right-angled glass prisms are used.the critical angel of ordinary glass is about 42 degree and a ray falling normally on face of such prism total internal reflection occurs and the ray is turned through 90 degree .examples:totally reflecting prisms replace mirrors in good periscopes,light can also be reflected through 180 degree by a prisms this happens in binoculars.
What are three ways that a person can manipulate light?
Using lenses to refract light rays in specific directions. Using mirrors to reflect light in desired angles. Using prisms to separate light into its different colors.
What optical components does a camera use?
Convex and concave lenses, and prisms.
Is lens a prism?
No. But small sections of lenses behave like prisms.
