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 happens when light passes through 2 prisms?
When light passes through two prisms, the light is refracted twice - once when entering the first prism and again when exiting the second prism. The second refraction can result in the light changing direction a second time, depending on the orientation and properties of the prisms.
What is an example of a light transmitting?
An example of a light-transmitting material is glass. Glass allows light to pass through due to its transparent properties, making it commonly used in windows, lenses, and fiber optics for transmitting light efficiently.
What surfaces can light bounce off of?
Light can bounce off of smooth and reflective surfaces like mirrors, glass, and metal. Rough and absorbent surfaces, like paper, fabric, and rough walls, are less likely to reflect light effectively. Sister surfaces that are used in imaging and optical systems for redirecting light include prisms and lenses.
What are two advantages of using prisms rather than mirrors?
Prisms can disperse light into its component colors, creating a spectrum, which mirrors cannot do. Additionally, prisms allow for more versatile light manipulation, including bending light at various angles without the loss of intensity, while mirrors primarily reflect light without altering its wavelength. This makes prisms ideal for applications in spectroscopy and optical devices.
Why are prisms and lenses used in some periscopes insted of mirrors?
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 can you use to change the path of light?
Glass and perspex prisms, and mirrors can change the path of light. Try to look up the law of reflection on google, it should be a great help!

What these are used for binoculars?
Binoculars are distinguished from telescopes through the use of "folded optics". That is, the light path is folded into the body, allowing a compact design. Rather than mirrors, prisms are used to reflect the light.
How do flat mirrors and curved mirrors reflect light?
how do mirrors reflect light
What effects does a prism have on light?
Prisms refract light.
What effect a prism have on light?
Prisms refract light.
Do mirrors absorbe light?
No, mirrors reflect the light instead of absorbing it.
What is used to bend light in binoculars?
Prisms are used in binoculars to bend and reflect light, allowing the viewer to see a magnified image. Binoculars typically use either Porro prisms or roof prisms to achieve this.
Used to bend light in binoculars?
In binoculars, prisms are used to bend light. These prisms typically come in two main types: Porro prisms and roof prisms. They allow for the compact design of binoculars while ensuring that the light path is straightened, providing a correct orientation of the image to the viewer. This bending of light is crucial for achieving a wide field of view and improved depth perception.
