Prisims
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.
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.
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.
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.
Concave mirrors are used in torch reflectors because they have the ability to focus light rays to a point, creating a strong and concentrated beam of light. This helps to increase the intensity and range of the light emitted by the torch, making it more effective for illuminating objects at a distance.

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!

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 mirrors reflect light
Prisms refract light.
Prisms refract light.
No, mirrors reflect the light instead of absorbing it.
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.
Yes light can travel through prisms. At some points it would occur total internal reflection and at some points there would be refraction of light.
