  1. Wave Properties and Sound Review

  2. True or False 1. A wave transports energy but not matter.

  3. True or False 2. As the frequency of sound waves increases, the wavelength of the sound waves decreases.

  4. True or False 3. Sound waves cannot travel through solids

  5. True or False 4. According to the Doppler effect, light from a star moving away from Earth will have a higher frequency than light from a star moving toward Earth.

  6. True or False 5. When two waves are in the same place at the same time, they combine to produce a single wave.

  7. True or False 6. Anything that moves up and down or back and forth in a rhythmic way is vibrating.

  8. 7. Sound waves • A.requirea medium. • C.arenot mechanical waves. • B.areunrelated to vibrations. • D.cantravel in a vacuum.

  9. 8. The medium seismic waves travel through is • A.avacuum. • C.air. • B.rocksand other materials inside Earth. • D.energy.

  13. 12. The frequency of a sound wave determines • A.thepitch of the sound. • C.howfast the sound travels. • B.howloud the sound is. • D.themagnitude of the compression.

  14. 13. How loud a sound is depends on • A.thewavelength of the sound. • C.theamplitude of the waves. • B.thepitch of the sound. • D.themedium.

  15. 14. The intensity of a sound describes • A.itsspeed. • B.itsloudness at a particular distance. • C.thedistance and medium through which it travels • D.themedium through which it travels.

  16. 15. The pitch of a sound is most closely related to the • A.frequencyof vibrations. • B.distancefrom the sound source. • C.mediumthrough which the sound travels. • D.intensityof the sound.

  17. 16. A change in pitch or wave frequency due to movement is known as _____________. • A.ultrasonicwaves • C.DopplerEffect • B.intensity • D.vibrations

  23. Name That Wave 21. A wave that causes the particles of the medium to vibrate perpendicularly to the direction the wave travels. 22. A wave that requires a medium through which to travel. 23. A wave that causes the particles of the medium to vibrate parallel to the direction the wave travels. 24. A wave caused by a disturbance in electric and magnetic fields that does not require a medium.

  24. Vocabulary Terms 25. Two or more waves in the same place at the same time. 26. A disturbance that transmits energy through matter or space. 27. The time required for a full wavelength to pass a certain point. 28. The number of vibrations that occur in a certain time frame. 29. The matter through which a wave travels.
