Student Exploration: Longitudinal Waves
Prior Knowledge Questions (Do these
BEFORE using the Gizmo.)
In many science fiction movies, an evil alien
spaceship explodes with an enormous
KABOOM!!
Suppose you were floating in space at a safe
distance from a large explosion such as the
supernova at left. Do you think you would you
hear anything? Explain.
I don’t think so, I think the sound doesn’t have
anything to vibrate to make the noise in space.
Gizmo Warm-up
No sounds can be heard in outer space
because sound waves require a medium, such
as air, to travel through. Sound waves are
examples of longitudinal waves, or waves in
which particles move back and forth in the same
direction as the wave.
You can use the Longitudinal Waves GizmoTM to
explore the behavior of sound waves. In the
Gizmo, an air-filled tube contains 24
evenly-spaced, airtight dividers. To begin, select
the Pulsed waves setting and the Open tube.
