Answer:
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.

Answer:
hiiii dude
Refraction is the bending of light form one medium to another medium
i.e. Rarer to denser
denser to rarer
example- glass slab
laws -
- The incident ray, the refracted ray and the normal to the surface at the point of incidence all lie in one plane
- the ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant.(Snell law)
- sin I/ sin r
mark as brainliast plz ☺️♥️
