Explanation:

LONGITUDINAL WAVE PRACTICE

1. Longitudinal waves transfer energy through particle motion, but the medium's particles only oscillate; energy propagates forward.
2. Confirmed correct: wave particles oscillate locally, not travel far.

AMPLITUDE & ENERGY

1. Wave energy is proportional to the square of amplitude, so higher amplitude = more energy.
2. Quiet sound has low intensity, linked to small amplitude of sound waves.
3. Loud sound has high intensity, linked to large amplitude of sound waves.

FREQUENCY & WAVELENGTH

For waves with constant speed (e.g., sound in air), frequency ($f$) and wavelength ($\lambda$) follow $v = f\lambda$, so they are inversely related.

COMPARE & CONTRAST

• Particle motion: Transverse waves have particles moving perpendicular to wave direction; longitudinal waves have particles moving parallel to wave direction.
• Examples: Common transverse waves include light/ripples; common longitudinal waves include sound/compression springs.
• Special parts: Transverse waves have crests (peaks) and troughs (valleys); longitudinal waves have compressions (dense regions) and rarefactions (spread regions).

PRACTICE QUIZ QUESTIONS

1. Waves transfer energy without moving net matter.
2. Compressions (dense particle regions) are a defining feature of longitudinal waves.
3. Larger wave amplitude corresponds to greater stored/transmitted energy.

Answer:

LONGITUDINAL WAVE PRACTICE

1. Energy (and the medium's particles vibrate in place)
2. Vibrate in Place (correct as written)

AMPLITUDE & ENERGY

1. b) more energy
2. a) small amplitude
3. b) large amplitude

FREQUENCY & WAVELENGTH

• When frequency increases, wavelength decreases
• When frequency decreases, wavelength increases
