According to Cargille labs, which makes liquids with refractive indices that match those of various substances, the exact value for acrylic is 1.4917. Refractive index of the second medium (in which the refractive ray travels) with respect to the first medium (in which the incident ray travels) is the ratio of sine of the angle of incidence to the sine of the angle of refraction. Refractive index is a property of a substance that expresses how light bends when it passes through that substance, as a result of change in speed.

To make the most effective and efficient use of edge-lighted acrylic shapes, … Refractive index for any medium is calculated as: n = velocity of light in a vacuum / velocity of light in medium. This is an inexpensive and dramatic way to visualize refractive indices, plus, this block can be used for critical angle reflection demonstrations. Are you a teacher? Also, the history of important scientists in physics can be both inspiring and informative. Refractive Index of Polymers and Blends. How can I calculate the speed of light in a medium if I know the refractive index? [1] These bends at the surface boundaries between air and the object are called refraction.
