Webrefractive index) to an optically denser medium (which has a high refractive index), its speed slows down and bends towards the normal. As water is optically denser than air, a ray of light entering from air into water will bend towards the normal. 2. Light enters from air to glass, having a refractive index 1.50. WebRefractive Index A refractometer measures the extent to which light is bent (i.e. refracted) when it moves from air into a sample and is typically used to determine the index of refraction(“refractive index” or “n”) of a liquid sample. The refractive index is a unitless number, between 1.3000 and 1.7000 for most compounds, and is

"At the atomic scale, an electromagnetic wave's phase velocity is slowed in a material because the electric field creates a disturbance in the charges of each atom (primarily the electrons) proportional to the electric susceptibility of the medium. (Similarly, the magnetic field creates a disturbance proportional to the magnetic susceptibility.) As the electromagnetic fields oscillate in the wave, the charges in the material will be "shaken" back and forth at the same frequency. Th… " - Define refractive index of water

Web10 years ago. No, if total internal reflection really occurs at every part i.e. if the angle of incidence is large enough, it should have nothing to do with refractive index or the nature of the cladding material. However, irregularities in the boundary between the core and the cladding fibre results in loss of intensity (attenuation).
