(of a material or object) See-through, clear; having the property that light passes through it almost undisturbed, such that one can see through it clearly.Examples: ""You make the glass invisible by putting it into a liquid of nearly the same refractive index; a transparent thing becomes invisible if it is put in any medium of almost the same refractive index.""; "The waters of the lake were transparent until the factory dumped waste there."
