Question

please explain the concept of bi prism in wave optics!!?​

Answer 1

Explanation:

Definition of biprism. : a triangular prism with vertex angle of nearly 180° used to obtain images of a single source in observing the interference of light. — called also Fresnel biprism.

A Fresnel Biprism is a thin double prism placed base to base and have very small refracting angle ( 0.5o). This is equivalent to a single prism with one of its angle nearly 179° and other two of 0.5 o each. The interference is observed by the division of wave front.

Answer 2

Explanation:

A Fresnel Biprism is a thin double prism placed base to base and have very small refracting angle ( 0.5o). This is equivalent to a single prism with one of its angle nearly 179° and other two of 0.5 o each. ... Monochromatic light through a narrow slit S falls on biprism , which divides it into two components.
