a. Crests (label on graph)

b. Troughs (label on graph)

c. Amplitude (label on graph): ________

d. Wavelength (label; crest to crest): __________

e. Frequency (waves/seconds): ______________

f. Period: _______________

3. Draw a wave diagram with:


a. An Amplitude of 9 meters, a wavelength of 5 meters, and a frequency of
2 Hz.
Name:______________________________________________ Period:______
4. Wind gusts create ripples on the ocean that have a wavelength of 5.00 cm and
propagate at 2.00 m/s. What is their frequency?

5. How many times a minute does a boat bob up and down on ocean waves that have
a wavelength of 40.0 m and a propagation speed of 5.00 m/s?

6. A wave traveling on a Slinky® that is stretched to 4 m takes 2.4 s to travel the


length of the Slinky and back again. What is the speed of the wave?

a. Using the same Slinky stretched to the same length, a standing wave is
created which consists of three antinodes and four nodes. At what frequency
must the Slinky be oscillating?

7. The following wave pulses are traveling at each other. Draw the resulting wave
when they meet.
Name:______________________________________________ Period:______
8. Using the figure below sketch the transmitted wave and reflected wave as the
pulse travels from string X to string Y.

a. If the wave pulse started on String Y how would the reflected and
transmitted waves differ, if at all?

b. How does the wave speeds compare in String X and String Y?

9. Draw a standing wave that would form in a tube open on both ends at the 4 th
harmonic. Label all nodes and antinodes.

10. If a wind instrument, such as a tuba, has a fundamental frequency of 32.0


Hz, what are its first three harmonics (overtones)? It is closed at one end. (The
overtones of a real tuba are more complex than this example, because it is a
tapered tube.)

11. How long must a flute be in order to have a fundamental frequency of 262 Hz
(this frequency corresponds to middle C on the evenly tempered chromatic scale)
on a day where the speed of sound in air is 344 m/s? It is open at both ends.
