Apr 13, 2011 · Answer 2) 2.0. The index of refraction = (speed of light in a vacuum (or air)) / (speed in material) = 3 x 10^8 / 1.5 x 10^8 = 2 Aim To determine the refractive index of Perspex. This was repeated a further four times and the mean of the angle of refraction was obtained for each angle of incidence.
Also called refractive index . American Heritage®... The effective index of refraction of the sol-gel silica waveguide was estimated to be 1.49 for the transverse electric (TE) mode.Jello Refraction Experiment: This experiment shows one way to find the index of refraction of Jello. Jello is a common delectable treat enjoyed by many kids. It is also a translucent material which makes it a perfect candidate for an index of refraction experiment.
