The refraction of light obeys two laws of refraction which were given by the Dutch scientist Willebrod Snell, so they are known as Snell's laws after his name.They are as followed :-

1⃣The incident stay, the refracted ray and the normal at the point of incidence, all lie at the same plane.

2⃣The ration is sine of angle of incidence (i) to the sine of angle refraction (r) is constant for a given media i. e., mathematically :

sin i/sin r = constant

Answer 2

Explanation:

$\huge \bf \red{answer...} \:$

Laws : ✅✅

⭕The incident ray, the normal and the refracted ray at a point of incidence all lie in the same plane.

⭕ When a ray of light passes through a rarer medium to a denser medium, the refracted ray is closed to the normal while the ray of light passes through a denser medium to a rarer medium, the refracted ray is away from the normal

⭕ An incident ray passing through the normal always goes straight.

Snell's law : It states that the ratio of sine of angle of incidence to the sine of angle of refraction for two mediums is always constant. This constant is known as the refracted index.

Refracted index = sin i/sin r##
