Engineering Physics by Dr. Amita Maurya, Peoples University, Bhopal. A Fresnel Biprism is a thin double prism placed base to base and have very small refracting angle 0. The interference is observed by the division of wave front. Determination of wave length of light As expression for fringe width is Biprism can be used to determine the wavelength of given monochromatic light using the expression. Experimental Arrangement.

The biprism consist of two active angled prisms with their bases in contact. Here two sources S1 and S2 are the virtual image of the fine slit S as shown in Figure 4. All are mounted on an optical bench. These are adjusted at the same height and can move and rotate as required. The light emerging from the slit fall on the biprism. The edge A of the biprism divides the incident wave front into two parts.

The distance d1 between Ex;eriment and B1 is measured by the micrometre eyepiece. Your advantages 1 year warranty curricula compliant quality — made in Germany individual service available experiment guides online more than 5. We try improving the quality of our products for every consignment we dispatch. Slit, width adjustable up to 1 mm. If experriment diverging beam of light strikes the edge of the biprism, two diverging coherent light beams are created which appear to emerge from two virtual slits and interfere on the far side of the biprism.
