WebMaterials with a high index of refraction will have a shorter focal length than those with lower refractive indices. For example, lenses made of synthetic polymers, such as Lucite (refractive index of 1.47), have a lower refractive index than glass (1.51) leading to a slightly longer focal length. Web11 dec. 2024 · Students determine the refractive index the an liquid using a simple technique using a semi-circular hollow block. Then they predict the refractive card of a material (a Pyrex glass tube) by matching it use the known refractive index of a liquid using the percent light transmission measurement. The homemade light intensity …

WebThe refractive index of air depends on the air density and thus vary with air temperature and pressure. Since the pressure is lower at higher altitudes, the refractive index is also lower, causing light rays to refract towards the earth surface when traveling long distances through the atmosphere.
