Refractive index lower than 1
WebRefractive index measurement is actually a measurement of the speed of light in a medium. The speed of light (usually denoted by c) is 299 792 458 m/s in vacuum. In other media the speed of light is lower than this value, and the refractive index, R.I., of a medium is a measure of how much the speed of light is reduced in the medium. The WebThe polymers are highly transparent, allowing almost all light in the entire visible spectral region to transmit through. Thin solid film of hb-P1 shows high refractive indices (RI = 1.6255-1.681) in the wavelength region of 400-1700 nm, extremely high modified Abb e number (ν D 0 = 1030.7), and very low optical dispersion (D 0 = 0.000 97).
