Refractive Index Definition & Meaning YourDictionary

WebRefractive index is the ratio of the velocity of light of a specified wavelength in air to its velocity in the examined substance. When the principle of measurement is used it may be defined as the sine of the angle of incidence divided by the sine of the angle of refraction. WebAug 24, 2015 · The higher the refractive index the slower the light travels, which causes a correspondingly increased change in the direction of the light within the material. What this means for lenses is that a higher refractive index material can bend the light more and allow the profile of the lens to be lower.
