Explain what is refractive index?

Refractive index can be explained using a simple analogy. Refractive index can be said as the density for light or can be said as optical density. Like if the density of a medium is high, it is tough for any object to pass through that medium. Similarly, if the optical density or refractive index of an object is high, it is tough for the light waves to pass through that medium.
