Question

which statements accurately describe mechanical waves? choose four correct answers.
an ocean wave moving through water is an example of a mechanical wave.
a transverse wave is a type of mechanical wave.
a mechanical wave does not carry energy through matter.
energy is transferred through vibrating particles.
a longitudinal wave is a type of mechanical wave.

Explanation:

1. "An ocean wave moving through water is an example of a mechanical wave": Mechanical waves require a medium (like water for ocean waves) to travel, so this is correct.
2. "A transverse wave is a type of mechanical wave": Transverse waves (e.g., water waves, seismic S - waves) are mechanical waves as they need a medium, so this is correct.
3. "Energy is transferred through vibrating particles": Mechanical waves transfer energy by causing particles of the medium to vibrate, so this is correct.
4. "A longitudinal wave is a type of mechanical wave": Longitudinal waves (e.g., sound waves in air) are mechanical waves as they propagate through a medium, so this is correct.

The statement "A mechanical wave does not carry energy through matter" is incorrect because mechanical waves do carry energy through the matter (medium) they travel in.

Answer:

• An ocean wave moving through water is an example of a mechanical wave.
• A transverse wave is a type of mechanical wave.
• Energy is transferred through vibrating particles.
• A longitudinal wave is a type of mechanical wave.
