WebThe higher the refractive index of a medium, the more strongly the light refracts. By way of illustration, a vacuum has a refractive index of 1.0, the refractive index of air (1013 mbar) … WebIt is noted that the refractive index of Jet A-1 is similar to the sensor’s glass substrate. As temperature decreases, the refractive index of the fuel increases and to a greater extent than the glass. This means that at sufficiently low temperature the TM mode is cut-off. This occurred below -12oC for dried jet fuel.
The refractive index is an important property of the components of any optical instrument. It determines the focusing power of lenses, the dispersive power of prisms, the reflectivity of lens coatings, and the light-guiding nature of optical fiber. Since the refractive index is a fundamental physical property of a substance, it is often used to identify a particular substance, confirm its purity, or measure its concentration. The refractive index is used to measure solids, liquids, and …
