Explanation

• Binoculars typically use Porro prisms, which are a type of reflecting prism that uses total internal reflection to redirect light.
• Porro prisms are named after their inventor, Ignazio Porro, and are widely used in binoculars and other optical instruments.

Explanation

Binoculars use a combination of lenses and prisms to magnify and redirect light, relying on total internal reflection to ensure minimal light loss and a bright, clear image.
