WebThe Index of Refraction ( IOR) is a value used to specify the way that light is scattered as it passes through a material. You are most familar with the “bent straw” effect when viewing a clear glass of water and a straw. That is because the light traveling through the glass of water is behaving differently than when it travels through air.

"WebThe Refractive Index - n - of a medium is a measure for how much the velocity of light is reduced inside the medium. The velocity of light in a medium can be expressed as v = c / n (1) where v = velocity of light in the medium (m/s, ft/s) c = speed of light in air or vacuum - approximately 3 108 m/s (or 299792458 m/s) n = refractive index " - Ior of materials
