WebFeb 15, 2024 · A biprism consist of two acute angled prism with their bases in contact. Light falling on the upper half of the biprism bends downwards and appear to come from S 1. The virtual images S 1 and S2 formed by refraction act as coherent sources. Why does Fresnel use biprism? The Fresnel biprism demonstrates the interference of light. WebBy dividing up the wave-front of a beam of light at the Fresnel mirror and the Fresnel biprism, interference is produced. The wavelength is determined from the interference patterns. Benefits.
