Question Describe biprism experiment to calculate the wavelength of a monochormatic light. HO-ED-D is an instrument that demonstrates how Fresnel’s Bi prism can be used to obtain fringes due to interference and to calculate the wavelength of monochromatic light.
Research quality modules of the instrument can be used for project works as experimeny.

Screen with Mount Model No: Defective items will be replaced free of cost. Reference Book Solutions [ 0 ].
We request your continued support in our endeavor to serve you better. It is about one and a half metre long, and a scale is marked along its length. Achromatic Lens with Mount Model No: The fringes would be formed in the region shown in the diagram.
Inform you about new question papers. When the refracting edge of the biprism becomes exactly parallel, the interference pattern consisting of alternate bright and dark bands appear in the field of view of the eyepiece. The apparatus consists of an optical rail on which components are mounted using posts, post holders and movable carriages. All components are made out of anodized aluminum and stainless steel to avoid corrosion. Repair or replacement will be made free of charge for products with defects in material and workmanship during this period.

Hence, the method of conjugate foci is used. We try improving the quality of our products for every consignment we dispatch. If your unit is out of warranty but needs repair, please contact us with details regarding the damage.
If a 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.
