Question

the model represents a sound wave.
sound wave
speaker ear
key

• air particle

which statement best describes the relationship between matter and energy in a sound wave?

1. particles of matter are transformed into other types of matter by energy in a sound wave.
2. energy in a sound wave transfers between particles of matter in a repeating pattern.
3. energy in a sound wave moves particles of matter from one place to another.
4. particles of matter transform into energy to produce a sound wave.

Explanation:

• Sound waves are mechanical waves that require a medium (matter like air particles here). Energy in sound waves is transferred through the vibration of particles. Particles oscillate (move in a repeating pattern) and transfer energy to neighboring particles, but the particles themselves don’t move from their original position (so option about moving particles is wrong), matter isn’t transformed into other matter or energy (so options about transformation are wrong). Thus, energy transfers between particles in a repeating (oscillatory) pattern.

Answer:

The option "Energy in a sound wave transfers between particles of matter in a repeating pattern." (assuming it's the second option, let's correct the numbering: let's say the correct option is B. Energy in a sound wave transfers between particles of matter in a repeating pattern. (adjusting the numbering error in the original, as the options seem to have repeated "1."; we'll identify the correct one by its content))
