SPECIFICATION

55937 Fresnel's Biprism Setup illustrates the phenomenon of interference of light. We can find the wavelength of monochromatic light source like LASER, Sodium lamp etc. Students can also understand the concept of interference, image formation and width of fringes. The Fresnel Biprism consists of two prism joined together to form an isosceles triangle. Light from the slit hits the prism and is refracted through each half of the prism. This light then interferes with itself to produce an interference pattern like Young's Double Slit.
