refractive index; index of refraction
A physical measure of how much light bends, or slows, when it passes into a material. A higher value means light is refracted more strongly.
ガラスの屈折率を測る。
To measure the refractive index of glass.
水とガラスでは屈折率が違う。
Water and glass have different refractive indices.
レンズの設計では材料の屈折率が重要になる。
In lens design, the refractive index of the material is important.
A physics term expressing how strongly a transparent medium bends light relative to a vacuum. Diamonds appear brilliant because of their very high refractive index.
COMMON COLLOCATIONS:
