Index of refraction of plastic
WebThe index of refraction for polystyrene is found to be 1.49 in Figure 2, and the index of refraction of air can be taken to be 1.00, as before. Thus, the condition that the second medium (air) has an index of refraction less than the first (plastic) is … Web19 jan. 2024 · The index of refraction, or refractive index, is a measure of how fast light rays travel through a given medium. Alternatively, it could be said that the refractive …
