Physics for IGCSE & O level - Rays And Waves (Section 7 - No. 16)
What determines the refractive index of a material?
The angle of incidence
The speed of light in a vacuum and the speed of light in the material.
The colour of light
The temperature of the material
Förklaring
The refractive index is determined by the ratio of the speed of light in a vacuum to the speed of light in the material.
