Answer:
There are two laws of refraction
1. The incidence ray, the refracted ray and the normal at the point of incidence lie in the same plane
2. the ratio of the Sine of angle of incident the Sine of angle reflection is a constant for any two given medium for the same colour of light.the constant ratio is called the refractive index of the second medium with respect to the first medium the second law of reflection is called snell law according to snell law,
sin i upon sign r equals to constant
