Not able to understand refractife index

ratio of sin of angle of incidence to the sinbof angle og refraction
If u wanna ask it for the sake of understanding then i would tell u how i see it. I connect refractive index to the internal structure and a bit of density thing. Refractive index is a relative term and when we say refractive index of a body we actually are pointing towards the relative refractive index with respect to vaccum.
Refractive index of a body is ratio of speed of light in the vaccum to that in the body. This is how it is defined.
Glass has higher index than water. So i sometimes try to relate it a bit with density (only saying in a rough idea) and internal structure. The more obstacle light faces inside a body,the more it gets deflected from its path and hence has to cover greater resultant path which appears as light's speed decreased inside the body.
3. light speed is less in a body havin more refractive index than lesser one.
2. Light bends towards the normal when it goes from rarer to denser medium.
1. The extent of its bending depends upon the difference in the refractive indexes of the two.
This is how i see it. Hope this side helps.
