Prisms are used in binocular Collect information about the why prisms are used in binocular

Answer 1

The prisms used in binoculars are basically blocks of glass that acts like mirrors. The prisms use internal reflections to bring the beam of light from the objective lens closer together and to correct the orientation of the image created by the objective lens.

Answer 2

Answer:

1. If 2 telescopes are mounted parallel to each other so that an object can be seen

by both the eyes simultaneously the arrangement is called binocular.

2. The length of each tube is reduced by using a set of totally reflecting prisms.

3. They provide intense, erect image free from lateral inversion.

fe- focal length eyepiece

4. Through a binocular we get 2 images of the same object from different angles at

same time.

5. Their super position gives the perception of depth also with length and breadth

6. Binocular vision gives proper 3D image.

7. By using total reflecting prisms there is no loss of intensity.
