Answer
(i) The incident ray and the refracted ray are on the opposite sides of the normal at the point of incidence and all three lie in the same plane. (ii) For a given pair of media, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant. If 'i' is the angle of incidence and 'r' is the angle of refraction, then $\frac{\sin i}{\sin r}=$ constant. This constant is called refractive index of a medium.
