1 1.[SP04-11 #55] The pitch of a sound made by plucking a guitar string is determined by the Ffrequency of the vibration produced Gstrength of the plucking force Hdistance between the strings Jshape of the guitar body

2 2.[SP04-10 #37] Which illustration best demonstrates compression waves?

3 3.[JY04-11 #14] When trying to spear a fish in water, a person needs to take into account the way light bends as it moves from water into air. The bending of light as it passes from one medium into another is known as Freflection Grefraction Hdiffraction Jpolarization

4 4.[SP03-11 #32] One tuning fork is struck and placed next to an identical fork. The two forks do not touch. The second tuning fork starts to vibrate because of Ainterference Bthe Doppler effect Cresonance Dstanding waves

5 5.[JY04-11 #7] Which wave has the greatest velocity?

6 6.[SP03-11 #44] According to the table, which workers have the greatest chance of experiencing significant hearing loss over time? APolice traffic officers BShoe-factory workers CRoad-construction crews DLibrary desk clerks

7 7.[SP03-10 #38] At 0°C sound travels through air at a speed of 330 m/s. If a sound wave is produced with a wavelength of 0.10 m, what is the waves frequency? F Hz G33 Hz H330 Hz J3300 Hz

8 8. A guitar player is seated next to a piano. The piano player strikes an E key on the piano. The guitarist reports that this causes the E string on his guitar to vibrate. What is the name of this phenomenon? A Polarization B Resonance C Reflection D Diffraction

9 9. A surface wave generated by an earthquake was recorded at Seismic Station 1. Forty seconds later the same wave was recorded at Seismic Station 2. What accounts for the time difference? F The origin of the wave is closer to Seismic Station 1. G The speed of the wave decreases with distance. H The wavelength is longer at Seismic Station 2. J The wave frequency increases when the wave passes through soil.

10 10. The diagram shows waves approaching a barrier. Which pattern will be formed after the waves pass through the opening in the barrier?

11 11. The speed of sound in human tissue is about 1600 m/s. If an ultrasound pulse takes 1.5 × s to travel through a tissue, what is the thickness of the tissue? F 2.4 km G 2.4 m H 24 cm J 24 mm

12 12. A tuning fork with a frequency of 256 Hz vibrates when struck. Because of these vibrations, a nearby tuning fork begins to vibrate without being struck. Which of the following best accounts for the vibration of the second tuning fork? F Resonance G Polarization H Diffraction J Refraction

13 13. When a DVD is read, laser light touches the DVD surface and is then measured at location A. What allows light to return to location A after striking the DVD surface? F Conduction G Refraction H Magnification J Reflection

14 14. An empty cup was tightly covered with plastic wrap, and a few grains of salt were sprinkled on top of the plastic. When a tuning fork was struck and placed slightly above the plastic wrap, the salt began to move. Which characteristic of waves does the movement of the salt best demonstrate? A Echo formation B Diffraction C Resonance D Specular reflection

15 15. Diverging lenses are useful to people who suffer from nearsightedness because the lenses can cause images of distant objects to be focused on the retina. Lenses allow images to be focused on the retina because of F diffusion G reflection H diffraction J refraction

16 16. Which label on the model represents a wavelength? FQGRHSJTFQGRHSJT

17 17. A surfer wishing to ride a big wave is most interested in a waves A rarefaction B compression C amplitude D wavelength

18 18. A diver on a springboard can increase the height of a jump by repeatedly flexing the knees with a rhythm that matches the springboards natural frequency. This is an example of A interference B reflection C resonance D polarization

19 19. Earthquake waves are detected by an instrument called a seismograph, and the data are recorded visually on a seismogram. To determine the location of an earthquake, scientists must determine the amount of time between the first arrival of the P wave and the first arrival of the S wave at the location of the seismograph. According to the data in the seismogram shown above, how much time elapsed between the arrival of the P wave and the arrival of the S wave? A 11 seconds B 25 seconds C 37 seconds D 90 seconds

20 20. Diagram 1 represents a wave. Diagram 2 represents the composite wave formed when a second wave interferes with the original wave. Which of the following best represents the second wave?

21 21. Which of the following indicates one wavelength of the wave shown above? A W to X B X to Y C W to Y D Y to Z
