* Elasticity: How much a material can deform under stress and then return to its original shape. More elastic materials allow sound waves to travel faster.
* Density: How much mass is packed into a given volume. Denser materials slow down sound waves.
General Range:
* Typical solids: Sound travels at speeds between 1,000 and 6,000 meters per second (3,300 to 19,700 feet per second).
Examples:
* Steel: Approximately 5,000 meters per second (16,400 feet per second).
* Aluminum: Approximately 6,400 meters per second (21,000 feet per second).
* Glass: Approximately 4,500 meters per second (14,800 feet per second).
* Rubber: Approximately 1,000 meters per second (3,300 feet per second).
Comparing to other mediums:
* Air: Approximately 343 meters per second (1,125 feet per second) at room temperature.
* Water: Approximately 1,480 meters per second (4,860 feet per second) at room temperature.
Key takeaway: Sound travels much faster in solids because the molecules are packed much closer together, allowing vibrations to transfer more efficiently.
