Prisms are used in binuculars. Collect information why prisms are used in binoculars.

Text Solution

Verified by Experts

1) Generally right angled prisms(or) biprisms are used in binoculars.
2) Prisms are used in binocular instead of mirrors for better reflections.
3) Prisms are increases the optical intensity and magnitude of objects.
4) Due to prisms size of binocular is reduced.
5) We can increase the reflection effeciency upto 95% at the similar cost of manufacturing by prisms.
