Question 41 pts
Which statement best describes how the particles of a medium behave when a mechanical wave moves through the medium?
Group of answer choices
Particles travel in the direction that is perpendicular to the motion of the wave.
Particles travel in the direction of the wave, away from the source of the wave.
Particles stay in one place as the wave travels past them.
Particles move as the wave passes them but do not move along with the wave.
Question 51 pts
Headphone earpieces can produce sounds that seem very loud to the listener. However, a person standing a meter away may not even be able to hear those same sounds. Why are these sounds so much quieter a short distance away?
Group of answer choices
The amplitude of the waves decreases as the sound spreads out and is absorbed by air.
The wavelengths of the waves are too short to reach a person standing a meter away.
The frequency of the sound is too high to travel a full meter through the air.
Sound waves from headphones do not use air as a medium and travel directly into your ear.
