What is the gradient of a graph of sin i (sine of incident ray) against sin r (sine of refracted ray)?

Ratio of sin i and sin r is constant and this graph will be a st line .
this ratio gives the refractive index which is different for different materials.

It's nothing but the refractive index of the denser medium w.r.t the rarer medium. If the rarer medium is air or vacuum (which is generally the case) then it's simply called the refractive index of the medium.
The refractive index can be used for many things...like determining the angle b which a ray of incident light will be refracted or the speed of light in the medium.

according to Snell's law of refraction, the ratio of sin i and sin r is a constant,which is termed as refractive index(mu).so the graph formed will be a straight line
