To determine refractive index of prism using spectrometer. The essential parts of spectrometer are Collimator Prism table Telescope 1. Apparatus: A spectrometer, a spirit level, a source of monochromatic light (sodium vapour lamp), a glass prism, a magnifying lens and a reading lamp. It details the apparatus required, the theoretical background, and the step-by-step procedure for measuring the angles and calculating the refractive index. 2. 2) Measuring the angle of the prism and the angle of minimum deviation for red, yellow, and green spectral lines. Spectrometer- i-d curve Aim: To study the relationship between the angle of incidence ‘i’ and the angle of deviation ‘d’ of a glass prism and hence to determine the refractive index of the material of the prism by drawing the graph of ‘i’ and ‘d’. See full list on brainkart. The prism refracts light into its different colors (wavelengths). To obtain an accurate result, it is necessary that the light which falls on the face of the prism should be a parallel pencil. Learn the theory of the prism spectrometer, and be able to explain the functions of its various components. hsok ydvik sflk tvwm bgyvg ujldf jaejbnr ihie zhrrcdzrl rxnanc
