Wave Vocab
A disturbance that moves energy from one place to another
What is a wave?
The top of a transverse wave
What is crest?
When frequency increases, wavelength…
What is decreases?
As amplitude increases, sound becomes…
What is louder?
A wave that moves up and down (perpendicular)
What is a transverse wave?
The distance between two corresponding crests
What is wavelength?
The bottom of a transverse wave
What is trough?
When frequency increases, amplitude usually…
What is stays the same?
Greater amplitude means more…
A wave that compresses and expands (moves parallel)
What is a longitudinal wave?
The height of a wave that determines its power
What is amplitude?
The distance from the origin to the crest
What is amplitude?
Higher frequency means waves are…
What is closer together?
Small amplitude produces sound that is…
What is quiet?
The part of a longitudinal wave where particles are close together
What is compression?
The number of waves that pass each second, measured in Hertz
What is frequency?
The starting point of a wave
What is origin?
Lower frequency means waves are…
What is farther apart?
Does amplitude change wavelength?
The part of a longitudinal wave where particles are spread far apart
What is rarefaction?
A material through which a wave travels
What is a medium?
The measure of the distance between two waves
What is wavelength?
Explain how changing amplitude does not change the frequency or wavelength
Amplitude is only how tall a wave is, changing the height will not impact the frequency or wavelength
Two sound waves travel through the same medium at the same frequency, but one is louder. What must be different?
What is amplitude?
Why does sound travel differently underwater than in air?
What is water is a different medium (denser), so sound speed and wavelength change?
