Laws of Refraction:
1. The incident ray, refracted ray and normal to the surface at the point of incidence all lie in one plane.
2. For any two given pair of media, the ratio of sine of angle of incidence to to the sine of angle of refraction is a constant. [Snell's Law]

Laws :

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

2. 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. [for any two mediums, the ratio of the sine of angle of incidence to the angle of sine of refraction is constant which is called refractive index.]

3. 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
