Fresnel’s BI-Prism Experiment (With Research Optical Bench)

Description

• Fresnel's Bi-prism Experiment: 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. Bi-prism produces interference pattern from a single source due to the creation of two virtual coherent sources as the light passes through the prism.

Experiment:

• To find the wavelength of the sodium light using bi-prism experiment

Product Detail:

• The apparatus consists of an optical Bench on which components are mounted using movable rides. For setting up the experiment, slit, eye piece and biprism are adjusted so as to obtain well defined bright and dark fringes. Here sodium vapour lamp is used as light source.
• Optical Bench: For Lloyd's Mirror Experiment, Research Optical Bench. This product is made from optimum quality heavy cast channel with a strong central rib. Offered bench is commonly used in different laboratories for performing various experiments. This product is offered with four accessories such as biprism holder, lens holder, micrometer eye piece and optical slit for effective performances.
