Explain fresnal bi Prisam?
Answers
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
its your answer

Explanation:
A Fresnel Biprism is a variation on the Young’s Slits experiment. The Fresnel bi prism consists of two thin prisms joint at their bases to form an isosceles triangle. A single wavefront impinges on both prisms; the left portion of the wavefront is refracted right while the right segment is refracted left. In the region of superposition, interference occurs as here two virtual sources exist.
thank you...
hope it helps buddy!!
