Student Exploration:
Waves
Vocabulary: amplitude, compression, crest, frequency, longitudinal wave, medium,
period, power, rarefaction, transverse wave, trough, wave, wavelength, wave speed
Prior Knowledge Questions (Do these BEFORE using the Gizmo.)
1. A buoy is anchored to the ocean floor. A large wave approaches the
buoy. How will the buoy move as the wave goes by?
The buoy will move because the wave will push it.
2. The two images show side views of ocean waves. How are the two sets of waves different?
The two images showing the
two different sides of the ocean
waves are different because
the first image of the wave is
higher than the second image
of the ocean wave.

, Gizmo Warm-up
Ocean swells are an example of waves. In the Waves
Gizmo™, you will observe wave motion on a model of a
spring. The hand can move the spring up and down or
back and forth.
To begin, check that the Type of wave is Transverse, Amplitude is 20.0 cm, Frequency is
0.75 Hz, Tension is 3.0 N, and Density is 1.0 kg/m. Click Play ( ).
1. How would you describe the motion of a transverse wave? In my opinion, I think that the
motion of this transverse wave is moving at right angles. Because, the speed stays the same and
the wave power doesn’t change either.
Click Pause ( ). Notice the crests (high points) and troughs (low points) of the wave.
2. Click Reset ( ). For the Type of wave, choose Longitudinal. Increase the Amplitude to
20.0 cm, and click Play. How would you describe the motion of a longitudinal wave?
I think, that the motion of this longitudinal wave is a wave that is going said to
side but in a slow speed.
Click Pause. Notice the compressions in the wave where the coils of the spring
model are close together and the rarefactions where the coils are spread apart.
