,Describe a sound as a pressure When a force pushes on a group of air
wave using the terms molecules, they move closer to the molecules
compression/peak, next to them (compression). The pressure
rarefaction/trough. from the first group causes the second group
to move away. At the same time, elastic forces
cause the first group to go back towards its
resting position. This creates a region of low
pressure (rarefaction). The second group, in
motion due to inertia, will press on the
molecules next to them (creating
compression), then snap back (creating
rarefaction). Alternating regions of high and
low pressure radiate out from a sound source.
, "When I produce a speech Inaccurate, sound passes energy through
sound, air molecules from my many molecules in a succession, sort of like a
lungs travel to your ear." Is this domino effect. The molecules themselves only
statement accurate? Why or why rock back and forth in a single location in
not? space, but the wave as a whole is transmitted
across long distances.
Describe the oscillatory When air molecules are set into motion, they
movement of particles in terms of oscillate back and forth around their resting
the interaction of inertia and position due to the opposing forces of
elastic forces. elasticity (ability to snap back to resting state
after force is applied) and inertia (wanting to
remain in motion).
