EQ: How do different mediums affect the speed of sound?

Sound. As an object vibrates it gives off energy to the particles of matter around it. These vibrations travel through air in a series of rarefactions.

Combining Sound Waves EQ: What happens when two or more sound waves interact?

Sound. Speed Factors State of matter  Fastest in a solid; slowest in a gas. Density  Faster in denser substances (iron versus copper). Elasticity 
