Properties of Sound

Multiple Choice

___________ is the maximum distance the particles in a medium move from their rest positions as the wave passes through the medium.

• intensity

• loudness

• amplitude

• energy

Multiple Choice

Which type of sound wave has the greatest energy?

• a wave that has a very low amplitude

• a wave that has a very high intensity

• a wave with particles that do not vibrate from their rest positions

• a wave with particles that vibrate a very short distance from their rest positions

Multiple Choice

___________ is how you perceive the energy of a sound wave.

• Loudness

• Amplitude

• Intensity

• energy

Multiple Choice

___________ is the amount of sound energy that passes through a square meter of space in one second.

• Loudness

• Amplitude

• Intensity

• energy

Multiple Choice

Which property of sound waves changes when you increase the volume on a car radio (increase in energy)?

• amplitude

• frequency

• speed

• wavelength

Multiple Choice

Which increases if the amplitude of a sound wave increases?

• pitch

• sound quality

• interference

• intensity

Multiple Choice

A normal conversation has an intensity of 60 dB and an MP3 player at peak volume has an intensity of 110 dB. How many times more energy does the MP3 player has?

• 100 times more

• 1,000 times more

• 10, 000 times more

• 100,000 times more

Multiple Choice

• 30 minutes

• 1 hour

• 2 hours

• 10 minutes
