I did read the wikipedia article, but didn't understand why the materials refractive index depends on polarization.Please explain me. Thank you.

Is there any relation between refractive index and polarization?

I read this section which is given below in our college notes. Effect of mass of medium: Mass gives inertia to the particle of the medium. It helps to store the wave energy in the form of kinetic and potential energies of disturbed particle and transfers it to neighboring particle with no or...

I read somewhere that for a wave traveling in a medium a particle (of medium) "gives"(I am not sure if that is the right word) energy to adjacent particle.Is this correct? And if it is why and how does this transfer take place? Also what role does inertia of particle play in wave propagation?
