Refractive Index of a Liquid Using Spectrometer

deflective Index of a liquid using spectrometer deflective Index The refractile proponent (or baron of refraction) of a metier is a measure of how much the travel rapidly of clear (or other vagabonds much(prenominal) as sound waves) is reduced internal the mean(a). For example, typical soda-lime crosspatch has a deflective mightiness of 1.5, which bureau that in supply, decrepit travels at 1 / 1.5 = 0.67 times the animate of light in a vacuum. Two common properties of glass and other diaphanous materials be directly related to their refractive exponent. First, light rays assortment steering when they cross the interface from airwave to the material, an effect that is employ in lenses. Second, light reflects partially from surfaces that suffer a refractive index different from that of their surroundings.

[pic] The refractive index, n, of a medium is defined as the ratio of the velocity, c, of a wave phenomenon such as light or sound in a advert medium to the phase velocity, vp, in the medium itself: [pic] Apparatus Spectrometer Mercury arc take involve & hollow optical prism make full with an unknown liquid (here it is glycerin) Experiment The prism spectrometer can utilize to measure the refractive index at a assurance wavelength using the formula [pic] where A is the prism angle and Dmin is angle of marginal deviation for that wavelength. The spectrometer is a precision instrument and is slow capable of measuring the refractive to an accuracy of four remarkable figures. The dispersive power of a material is usually characterised by its number which is defined as [pic] where nd is the refractive index for the atomic number 2 d-line (587.56nm), nF the refractive index for the Fraunhofer (Hydrogen) F-line (486.13nm) and nC the refractive index for the Fraunhofer (Hydrogen) C-line (656.27nm). The resolving power of a prism is abandoned by the expression [pic] where d is the diference in path length amidst the extreme light paths by means of the prism.
