Warping light, sound, and time?

mirage on rail road track warp visible light air temperature differential

Why do small differentials in air temperature warp visible light?  Index of refraction [1].   

An earlier post on Realneo wondered whether an invisibility cloak could be made from wire - the air temperature differential around the wires on the corn crib causes a visual moire effect [2].

Wouldn't the air temperature differential also warp sound?

What about time?
