Waves: Sound Wave Properties

What types of medium(s) can sound travel through?

• All of them!

• solids

• liquids

• gases

What mathematical term can we use to describe the relationship between energy and matter movement in a longitudinal wave?

"Energy and the wave are moving in the same direction"

• Perpendicular

• Parallel

• Right Angle

What is the name for the bunched up region of air particles in the sound wave?

• Rarefaction

• Compression

What part of your EAR picks up pressure waves (sound waves)?

• Cochlea

• Ear Drum

• Those 3 Bones

• Your Ear Lobe

Pitch is directly related to the ___________ of a wave.

• Frequency

• Loudness

What characteristic of a wave did we learn is related to the Intensity or Loudness of a sound?

• Frequency

• Wavelength

• Amplitude

What is the Doppler Effect

• As a sound is closer to you the pitch is higher. As the sound moves away from you the pitch is lower.

• As a sound is closer to you the pitch is lower. AS the sound moves away from you the pitch is higher

Now our wavelength is getting longer because the waves are stretching out. This make the _________ lower as well as the pitch we hear. 

• Amplitude

• Loudness

• Frequency
