Spectrometer experiment to find refractive index of prism. Principle When a beam of light strikes on the surface of transparent material (Glass, water, quartz crystal, etc. ), the portion of the light is transmitted and other portion is reflected. The spectrometer consists of a slit, collimator, viewing telescope, arrangement for measuring the angle between collimator and scope, and a table for the prism. The Prism Spectrometer In this experiment you will determine the refractive index n(λ) of a glass prism by measuring the minimum deviation angle D(λ) with the spectrometer. Minimum Deviation: The angle at which light passes through the prism with the least distortion, used to calculate the refractive index. The document provides details of the Measurement of refractive index of glass by prism spectrometer Introduction – A prism spectrometer A prism spectrometer is an instrument for observing spectra and measuring angles of deviation of light by a prism. The calibration of a prism spectrometer is carried out with known spectral lines from vapor lamps or laser light. The strongest line is at 589 nm (yellow) and the other spectral lines that can be seen are mainly a green and a red line at the side of yellow line, plus two other transitions in the blue side of the spectrum. The spectrometer is one convenient way to do this. It details the apparatus required, the theoretical background, and the step-by-step procedure for measuring the angles and calculating the refractive index. pvliz arxa zgde bwrnm nmlwc jdcjc osji zlx dydub zej
