Question

Why does sound waves travel faster in salt water than in fresh water?

Answer 1

Higher bulk modulus means faster speed of sound. Salt water is about 2-4% more dense than fresh water. But it also has a bulk modulus that's about 9% greater than that of fresh water! ... It makes sense that higher density means lower speed of sound because it's more mass that has to vibrate when the sound wave passes.

Answer 2

Since there are more solid's if you get what I mean..
