Q

What does Snell's law of refraction state about the ratio of the sine of the angle of incidence to the sine of the angle of refraction for a given colour and pair of media?

✓ Answer: C It remains constant.
Snell's law states that for fixed media, sin i/sin r is constant for a given wavelength. This relation describes refraction at the boundary of two media.
