index of refraction

ریشه

From the Latin 'index' (pointer, informer, list) + 'of' (indicating a relationship) + 'refraction' (the bending of light as it passes through different materials).

مثال

• The index of refraction determines the speed of light in a given material.
• Different materials have different indices of refraction, affecting how light travels through them.
• The index of refraction is used to calculate the angle at which light is bent when passing through a medium.
