1) On a piece of graph paper where each square represents 1 meter draw the
following waves. For each draw a line of equilibrium and label the amplitude
and the wavelength.
a. Draw 1 whole wave with an Amplitude 5 m, Wavelength 10 m
b. Draw 2 whole waves with an Amplitude 7m, Wavelength 12 m
c. Draw 1/2 wave with an Amplitude 8 m, Wavelength 14 m.
d. Draw 1.5 waves with an Amplitude 6 m, Wavelength 16 m.
e. Draw 2.5 waves with an Amplitude 7 m, Wavelength 8 m.
2) A transverse wave is transporting energy from east to west. The particles of
the medium will move_____.
a. east to west only
b. both eastward and westward
c. north to south only
d. both northward and southward
3) A longitudinal wave is transporting energy from east to west. The particles
of the medium will move_____.
a. east to west only
b. both eastward and westward
c. north to south only
d. both northward and southward
4) Why is sound a longitudinal wave but a stadium wave is a transverse wave?
Explain the difference.
5) When playing the parachute game, picture below. Students make waves
through the parachute. Explain what measurement of the wave has changed
out of (v, λ, f, and amplitude) when the students changed the following
actions.
a. Students move their hands up and down harder using more force, but
still at the same frequency.
b. Students move their hand more up and down more frequently.
c. Students move their hands less up and down less frequently.
d. Students only pull the parachute tighter.
6) A science fiction film depicts inhabitants of one spaceship (in outer space)
hearing the sound of a nearby spaceship as it zooms past at high speeds.
Critique the physics of this film.
7) Consider the diagram below in order to answer questions a,b,c.
a. The wavelength of the wave in the diagram above is given by letter ______.
b. The amplitude of the wave in the diagram above is given by letter _____.
c. Indicate the interval that represents one full wavelength.
8)On the diagram below choose 3 intervals, which represent one wavelength.
8) Draw the reflection of a wave off of the following boundaries: (You need to
decide if the boundaries are fixed or loose)
a. A water wave crest reflects off a pool wall
b. A wave trough in a violin reflects off of the bridge near the bottom of
the violin.
c. A wave crest is sent along a tug of war rope while it is being pulled by
both teams and reflects off of the last players hands.
d. A wave trough is sent through the ground during an earthquake and
hits a break in the tectonic plates where it reflects back towards the
epicenter.
