Question

select all the statements that are true of the physical aspects of sound. wave patterns of sound become stronger between the source and our ears. air molecules move in regular, wavelike patterns. a medium such as air or water is necessary to conduct sound to our ears. it is created by a vibrating source.

Explanation:

1. Sound waves lose energy as they travel, so their strength (amplitude) decreases, not increases, from source to ear.
2. Sound propagates via longitudinal waves, where air molecules oscillate back-and-forth in regular, wave-aligned patterns.
3. Sound is a mechanical wave, requiring a medium (solid, liquid, gas) to travel; it cannot move through a vacuum.
4. Sound originates from vibrating objects, which transfer energy to the surrounding medium to create sound waves.

Answer:

• Air molecules move in regular, wavelike patterns.
• A medium such as air or water is necessary to conduct sound to our ears.
• It is created by a vibrating source.
