Which of the following statements about sound waves is correct?
A. Sound waves can travel freely through a perfect vacuum.
B. Sound waves are transverse waves in gaseous media.
C. Sound travels faster in steel than in dry air at room temperature.✓ Correct Answer
D. The velocity of sound decreases with an increase in medium temperature.
💡 Solution & Explanation
Sound waves are mechanical waves requiring a material medium for propagation and travel significantly faster in dense elastic solids like steel compared to gases because elasticity and density determine acoustic speed. They cannot propagate through empty space due to the absence of oscillating particles. Furthermore, the speed of sound increases directly with the absolute temperature of the medium.
