The Travel of Sound Waves

Energy and Change

It it interesting that you when you are underwater you hear sounds made outside the water. How do liquids affect how sound travels? Does the thickness of a liquid affect how sound travels? This project found that liquids increase the volume of sounds traveling through them and it was most affected by thicker liquids.
