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 they weaken, not strengthen, from source to ear.
2. Sound is a longitudinal wave; air molecules oscillate back and forth in regular, wave-aligned patterns.
3. Sound requires a medium (solid, liquid, gas) to travel, as it propagates via particle vibrations.
4. All sound originates from a vibrating object that disturbs surrounding medium particles.

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.
