Science Fact

Sound Waves

Sound waves travel through the air at 767 miles per hour. However they travel even faster through liquids and solids because the molecules are more tightly packed together, giving the sound waves a speedier path.

For instance, sound waves travel through fresh water at 3,315 mph, through wood at 8,859 mph and through steel at 13,332 mph.
