Paper index of refraction

WebCalculate the index of refraction of the unknown material. Step 1: Identify the index of refraction and wavelength in the medium of the known refractive index. n1 = 1 λ1 = 7m Step 2:... 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 …
