what are the law of refraction ?
senoza1415:
1. ANGLE OF INCIDENCE IS EQUAL TO ANGLE OF REFRACTION
2. THE INCIDENT RAY , NORMAL (at the point of incidence ) , REFRACTED RAY ALL LIE ON THE SAME PLANE
THESE R THE LAWS FOR REFLECTION
FOR REFRACTION : (i) Incident ray (IP) & Refracted ray (PR) lie on either side of the normal (MPN') to the boundary of separation.
(ii) IP, NPN' & PR lie on the same plane which is called the plane of incidence.
(iii) i (angle of incidence) > r (angle of refraction), when the light enters from rarer to denser medium and i' < r' for the converse case.
(iv) Sine of i bears constant ratio to sine of r for the given pair. The constant is called the refractive index of medium 2, with respect to

snell's law is a formula used to describe the relationship between the angles of incidence and refraction when reffering to light or other waves passing from a boundary between isotopric media such as water, glass and air.

when incident ray is passing threw a glass slab when incident ray becomes bend threw the glass slab is called law of refraction
