Acoustics: Order of increasing speed of sound across media Considering typical room conditions, arrange media so that the velocity of sound increases in the correct order from least to greatest. Choose the correct option.

Difficulty: Easy

Steel, Water, Air
Air, Water, Steel
Water, Air, Steel
Air, Steel, Water

Correct Answer: Air, Water, Steel

Explanation:

ConceptSound speed increases with bulk modulus and decreases with density; generally v_gas < v_liquid < v_solid.

Typical valuesAir ≈ 343 m/s; Water ≈ 1500 m/s; Steel ≈ 5000 m/s.

Final AnswerAir, Water, Steel
