collect information from the prism why are they used in binoculars
Answers
as light travels in a straight line
Answer:
An optical prism is a transparent optical element with flat, polished surfaces that refract light. At least one surface must be angled—elements with two parallel surfaces are not prisms. The traditional geometrical shape of an optical prism is that of a triangular prism with a triangular base and rectangular sides, and in colloquial use "prism" usually refers to this type. Some types of optical prism are not in fact in the shape of geometric prisms. Prisms can be made from any material that is transparent to the wavelengths for which they are designed. Typical materials include glass, plastic, and fluorite.A dispersive prism can be used to break white light up into its constituent spectral colors (the colors of the rainbow). Furthermore, prisms can be used to reflect light, or to split light into components with different polarizations.
Prisms are used in binoculars for one primary purpose; which is to correct the inverted and laterally inverted image that is produced by the objective lens and the eyepiece lens. This is because objective lenses produce an image that appears upside down or laterally inverted.
