Answered by GPT-5 mini AI
fastest; slowest

Reason: wave speed in a material depends on its stiffness (elastic modulus) and density — solids are much stiffer than gases, so mechanical waves (e.g., sound) travel fastest in solids and slowest in gases (air ≈343 m/s, water ≈1480 m/s, steel ≈5960 m/s).
