<strong>Waves</strong> <strong>can</strong> <strong>be</strong> <strong>classified</strong> <strong>by</strong> <strong>how</strong><br />
<strong>they</strong> <strong>move</strong>.<br />
<strong>Waves</strong> <strong>have</strong> measurable<br />
properties.<br />
Crest<br />
TRANSVERSE<br />
LONGITUDINAL<br />
Rest<br />

<strong>move</strong>ment of wave is<br />
perpendicular to<br />
<strong>move</strong>ment of medium<br />
<strong>move</strong>ment of wave is<br />
parallel to <strong>move</strong>ment<br />
of medium<br />
Longitudinal <strong>Waves</strong> Have the<br />
Same Characteristics<br />
Which wave has a shorter wavelength?<br />
Which wave has a higher amplitude?<br />
How do you know?<br />

<strong>Waves</strong> <strong>have</strong> measurable<br />
properties.<br />
Frequency is the num<strong>be</strong>r of waves passing a<br />
point in a certain amount of time.<br />
Notice what happens to wavelength as<br />
frequency decreases...<br />
