Remember answers can be found in your wave unit notes/handouts/graded assignments and
book.
True or False. If the statement is false then write the word in the blank that would correct the word in italics to
make the statement true
1. __________A wave is a disturbance that transmits matter through a medium.
2. __________The time for a complete swing of a pendulum is its frequency.
3. ___________The amplitude of a wave is the vertical distance from the midpoint to either
the crest or trough of the wave.
4. ___________The distance between successive identical parts of the wave is its wave
speed.
5. ___________The number of times a wave vibrates each second is its period.
6. ___________The unit of the period of a wave is the hertz.
7. ___________As a light source is coming towards you, you see light of a frequency
higher than it really is.
8. ___________A pulse of compressed air that is part of a sound wave is a rarefaction.
9. ___________Even a steel bridge can collapse because of resonance.
10. ___________Light travels faster in glass than it does in a vacuum.
11. __________Nodes in a standing wave are the result of constructive interference.
12. __________A sonic boom happens at the instant when an object exceeds the speed of
sound.
(speed = frequency x wavelength) (frequency = 1/period)
13. A boat at anchor is rocked by waves whose crests are 20 m apart and whose speed is 10
m/s. How often do these waves reach the boat (frequency)?
14. Waves in a lake are 2 m in length and pass an anchored boat 0.5 seconds apart. What is
the speed of the waves? (hint: find frequency first)
15. What is the period of a sound wave whose wavelength is 2 meters (v= 340 m/s)?
16. What motion creates waves?
17. What are two types of mechanical waves?
18. What is the direction of motion for the particles in a transverse wave?
19. What is the direction of motion for the particles in a longitudinal/compressional wave?
20. What mediums do transverse waves go through? Order them from fastest to slowest.
21. What mediums do longitudinal/compressional waves go through? Order them from
fastest to slowest.
22. Draw a transverse wave. Label crest, trough, wavelength, and amplitude.
23. Draw a longitudinal/compressional wave. Label compression, rarefaction, and
wavelength.
24. Describe how to measure the frequency of a wave.
25. What two factors affect the speed of sound? Why?
1. Temperature & ___________________________
2. Why? _______________________________________________________________
