Suggestions for this week's quiz (Unit 12 Quiz):

This week's quiz on Unit 12 material is tentatively scheduled for Friday, March 20. The quiz will be a one-page quiz (maybe more), covering both sides of a single sheet of paper. The equations for the speed of a wave (v=f*lambda), the frequency-period relationship, v=d/t, and fn = n*f1 will be given. Other than a calculator, no other helps will be provided nor allowed. Students can expect the following concepts, skills, and problem-types to be assessed on this quiz:

  1. An understanding of the nature of a sound wave as a mechanical wave whose vibrational motion forces particles of the medium to vibrate longitudinally, thus creating regions of high pressure (compressions) and low pressure (rarefactions).
  2. An understanding of the physical properties of sound waves such as the amplitude, frequency, speed, wavelength, and intensity; an ability to perform relatively simple computational problems involving wavelength, frequency, speed, and period; an ability to use the deciBel scale to relate the intensity rations of two given sounds.
  3. An understanding of the basic behaviors of sound waves such as reflection, diffraction, refraction, interference, resonance, and (most importantly) the Doppler effect.
  4. An ability to use the speed = distance/time equation in order to solve computational problems involving the echoing (i.e., reflection) of a sound wave off a barrier.
  5. An understanding of the concepts of natural frequency, forced vibration, and resonance; an ability to relate the resonance mode (or harmonic) of a vibrational system (guitar string, air column or other mechanical object) to the standing wave patterns established by waves within that system; an ability to relate the frequency and/or wavelength of the the fundamental (first harmonic) to the frequency or wavelength of the other harmonics of a vibrational system.
  6. An ability to use the v = f*lambda equation, a standing wave diagram, and the length-wavelength relationship to solve computational problems involving the three types of instruments we have discussed: open-end air columns, closed-end air columns, and stringed instruments.
  7. An understanding of standing wave patterns including the ability to explain how a standing wave is formed from two individual interfering waves; an ability to diagram standing wave patterns for the first five harmonics of a string which is fixed at both ends; an ability to identify the nodes and anti-nodes in a standing wave pattern and to relate the length of the string to the wavelength of the wave for any given harmonic.
  8. An understanding of previous wave concepts from Unit 11. Use the link below to see the Studying Suggestions for the Unit 11 quizzes.
