Based on this information, in which substance is the speed of sound waves likely the greatest?
A.
air
B.
water
C.
steel
D.
copper
A. air
- The speed of sound waves is fastest in solids, with steel and copper having higher densities than air and water. Within the options given, air has the lowest density and therefore the speed of sound waves is likely the greatest in air.
