Hi, speed of sound in denser medium is greater as compared to light wave. can any one explain this in terms of refraction? thanx in advance

Nope. Sound waves are mechanical waves and light waves are electromagnetic, and so sound waves have no analogy to refraction of light waves. The factors that govern the speed of sound are the mechanical stiffness and density of the medium:


whereas the factors that govern the speed of light are the electric and magnetic constants of the medium:



These are completely different phenomena.
