Wave Properties
Complete each sentence by circling the correct answers and crossing out the incorrect answer.
1. The amplitude of a wave can be measured from the (medium, crest) or the (trough, wavelength) to
the rest position of the wave’s medium.
2. Waves with greater amplitudes carry (more, less) energy than waves with smaller amplitudes.
3. The wavelength of a transverse wave is often measured from (crest to crest, crest to trough).
4. The number of waves that pass a point in one (second, minute) is the wave’s
(amplitude, frequency).
5. Waves with longer wavelengths have a (lower, higher) frequency and waves with shorter wavelengths have a (lower, higher) frequency.

II. Concept Review
If the underscored word or phrase makes the sentence true, write “TRUE” in the space provided. If the
underscored word or phrase makes the sentence false, write the correct term or phrase in the space provided.
9. In a longitudinal wave, the medium travels at right angles to the
direction of the wave itself.
10. The amplitude of a sound wave is the number of compressions that
pass by a point in one second.

III. Skills/Process Review
Answer the following questions in phrases or complete sentences.
17. In the Find Out! activity, you made a wave by having several students sit in a large circle and
raise and lower their hands in a continuous motion. Using the data in the table below from a
similar activity, calculate the speed of the wave.
Distance around the circle
36 meters
Time for a pulse to travel around the circle
12 seconds
18. In the table, what happens to the speed of the wave as the number of pulses increases?
19. In the table, what is the wavelength when three pulses are going around the circle, evenly
spaced? Two pulses?
