About optical prism spectrometer - Lab Report ExampleThose colors emanated from the, white, Hydrogen and Mercury light sources.The main target of carrying out this study on prisms is to learn the aspects of prism spectrometer theory so as to invoke the ability of explaining the practicability of its components. This was mainly achieved through observation of the mercury spectrum discharge lamp while taking later(prenominal) angle of deviation records regarding the spectral lines. This hence creates the capability of determining the refraction index finger of the given looking glass prism for a number of wavelengths. It also gives insights on how to utilize the calibrated prism for the ultimate criterion of unknown wavelengths. Finally, it enables one to make a general observation regarding color sensation that is ca apply by the wonted light of specific wavelengths.The main tool that is used in this lab experiment is the spectroscope. This is an instrument that is used for pro duction an ultimate viewing of spectra. It is often comprised of three main parts that includes a collimator for production of replicate light beams, a prism that is majorly responsible for light dispersion towards the spectrum, and the telescope that is ultimately meant for spectrum examination (Gutierrez-Vega, Julio et.at, 2007).When in that location is transmission of light beam from air to the glass, the bending of the ray occurs with accordance to the Snells law. Therefore this can be summarized by an equation that is stated as sin q air = n sin q glass whereby the ensuant measure of subsequent angles is done on the normal surface in which n refers to the refraction index of the entire glass. The refraction index is hence a dimension-less value and is simply a clear measurement of the intensity in which the medium can bend light. The increase in the size of n is instanter proportional to the increased bending of light. The usual refractive index of air is always 1. For a gl ass, n often varies from the value of between 1.3 and 1.8,
