Speed of sound:

• The speed of sound varies from substance to substance.

• Typically, sound travels most slowly in gases, faster in liquids, and fastest in solids.

• Sound travels fastest in solids because the molecules are tightly packed together, allowing sound waves to move faster

• In exceptionally stiff materials such as diamond, sound travels at 12,000 m/s.

• The speed of sound in steel is 6,000 meters per second.
