Question

how does the speed of sound waves change in different media?
sound waves travel at constant speeds in solids, liquids, and gases.
sound waves travel fastest in gases, slower in liquids, and slowest in solids.
sound waves travel fastest in liquids, slower in solids, and slowest in gases.
sound waves travel fastest in solids, slower in liquids, and slowest in gases.

Explanation:

Sound is a mechanical wave that requires a medium to travel. In solids, the particles are closely packed, allowing sound waves to transfer energy more quickly through frequent collisions. Liquids have more spaced - out particles than solids but are still closer than gases. Gases have the most spaced - out particles, so sound waves travel slowest in them.

Answer:

Sound waves travel fastest in solids, slower in liquids, and slowest in gases.
