Question

sound waves move the slowest through which medium?
○ water
○ ice
○ air
○ wood

Explanation:

Sound waves travel by vibrating particles. In gases (like air), particles are far apart and have less interaction, so wave propagation is slower. Liquids (water) and solids (ice, wood) have closer particles, allowing faster sound movement. Among the options, air is a gas with the least dense particle arrangement for sound to travel through, resulting in the slowest speed.

Answer:

C. air
