Laws of Refraction NCERT Class 10 Science Definition of refraction : Refraction is the bending of light from one medium to another. The density of the medium that refracts light rays is also a factor in refraction . The more dense medium is referred to as a denser medium, whereas the less dense material is referred to as a rarer medium. The refraction law As a result of this basic experiment, we may deduce the laws of refraction listed below — 1. In the same plane as the incident ray, the refracted ray, and the normal to the interface of two transparent media at the point of incidence. 2. For the light of a given colour and a given set of media, the ratio of the sine of the angle of incidence (Sine I to the sine of the angle of refraction (Sine r) is a constant (Sine r). Snell's law of refraction is another name for this law. (This is also true for the angle 0 < I< 90 o ) 3. If I is the incidence angle and r is the refraction angle, then Constant = Sine I / Sine R Another imp
