The index of refraction (n) for any substance is the speed of light (c) over the value of speed of light through a medium (v). The value for Lucite is roughly 1.5, meaning that speed of light in Lucite is 2.00×108 m/s.Click to see full answer. Thereof, what is the index of refraction of acrylic?According to wikipedia, the accepted index of refraction for acrylic is 1.490-1.492. According to Cargille labs, which makes liquids with refractive indices that match those of various substances, the exact value for acrylic is 1.4917. what is the index of refraction of zircon? The index of refraction of a cubic zirconia is 2.2 which is almost as high as the diamond’s 2.4. Just so, what is the index of refraction of the plastic? Most plastics have refractive indices in the range from 1.3 to 1.7, but some high-refractive-index polymers can have values as high as 1.76. For infrared light refractive indices can be considerably higher. Germanium is transparent in the wavelength region from 2 to 14 µm and has a refractive index of about 4.How do you find the index of refraction? How to find the index of refraction Determine the speed of light in the analyzed medium. Divide the speed of light by this value. The obtained value is the refractive index of the medium. You can use this value to calculate the angle of refraction, using our Snell’s law calculator.
