| 1. | Lead has a high refractive index; it makes glass sparkle,
|
| 2. | Variations in the water content alter the refractive index of honey.
|
| 3. | Most materials used for LED production have very high refractive indices.
|
| 4. | Traditionally refractive index and density were also important for substance identification.
|
| 5. | This can lead to under / overcorrection of the refractive error.
|
| 6. | This lowers the refractive index, defocusing the propagating light beam.
|
| 7. | Examples of refractive error are myopia, hyperopia, and astigmatism.
|
| 8. | Temperature has a very important influence on the refractive index measurement.
|
| 9. | As for refractive index, that's a good one!
|
| 10. | This then gives rise to the variation of the refractive index.
