5 Matching questions

  1. what does sound need to travel
  2. units of density
  3. what happens to the molecules in a medium as sound waves pass through?
  4. what do waves do
  5. units of distance
  1. a sound must travel through a medium, it cannot travel through a vacuum
  2. b the molecules are alternately compressed and rarefied (stretched apart)
  3. c kg/cm cubed
  4. d all waves carry energy
  5. e cm,mm

5 Multiple choice questions

  1. there are 7 acoustic parameters: period, frequency, amplitude, power, intensity, wavelength, propagation speed----wif papp
  2. particles move in the same direction that the wave propagates
  3. the resultant wave is smaller (of lesser amplitude) than either one of its components
  4. particles move in a direction that is perpendicular (at right angles) to the direction that the wave propagates
  5. the interference of a pair of in phase waves forms a single wave of greater amplitude than either of its components--the resulting wave is larger than its components

5 True/False questions

  1. how does ultrasound worksound pulses through biologic tissue or media and reflections arising from structures in the body return to the xducer and are processed into images


  2. what kind of line does sound travel instraight or longitudinal


  3. how are sound waves identifiedsound must travel through a medium, it cannot travel through a vacuum


  4. what is acoustic propagationthe effects of the medium upon the sound wave (compression and rarefication)


  5. interferencewhen multiple beams arrive at an identical location at exactly the same time and thereby lose their individual characteristics and combine to form a single wave
