plzz give the correct answ
Answer:
the principle that for a ray, radar pulse, or the like, that is incident on the interface of two media, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the velocity of the ray in the first medium to the velocity in the second medium and the incident ray.
Laws of refraction state that: The incident ray, reflected ray and the normal, to the interface of any two given mediums; all lie in the same plane. The ratio of the sine of the angle of incidence and sine of the angle of refraction is constant.
