Sound Waves and Wave Vocabulary

Material (matter) through which a wave travels

• medium
• Doppler Effect
• sound
• pitch

How high or low a sound is; depends on the frequency (greater frequency= higher pitch)

• pitch
• frequency
• sound
• medium

A wave in which the vibration is in the same direction as that in which the wave is traveling; sound waves

• longitudinal wave
• ocean wave
• transverse wave
• mechanical wave

The part of a longitudinal wave where the particles of the medium are close together.

• rarefaction
• compression
• crest
• trough

A part in a longitudinal wave where the particles are spread apart

• compression
• rarefaction
• crest
• trough

A disturbance that transfers energy from one place to another without transferring energy

• wave
• trough
• pitch
• sound

The term for how loud or soft a sound is:

• pitch
• volume
• sound
• medium

Which feature of sound is determined by amplitude?

• Pitch
• Smoothness
• Loudness

If the distance represented by the letter A (the amplitude) were increased, how would it change the sound?

• The sound would be higher. 
• The sound would be lower. 
• The sound would be softer. 
• The sound would be louder. 

When a sound is louder what measurement gets bigger?

• Frequency 
• Amplitude 
• Wavelength 
• Crest
