About This Product
Fresnel's biprism experiment is the basic example of common path interference by division of wavefront. Light from a slit passes through two side-by-side prisms of very shallow angle and is split into two almost parallel beams. A convex lens makes the beams overlap, and they then behave as if they came from two virtual sources side by side.
