How do binoculars work?

1 Answer

Answer:

Binoculars are two small refractor telescopes aligned together so that you can use two eyes for observation.

Explanation:

Light from the objective entering the binoculars gets redirected through two prisms and go to eyepieces, where the image is formed.

As the binoculars have two objectives, they collect more light than single-lens telescopes. There are two numbers listed on a pair of binoculars,.like this: #10xx 50#, #7 xx30#, etc.

The first number is the diameter of the objective in millimeters and the second number is the magnification. Large binoculars need a tripod otherwise the image will be shaking.
