Henderson's Regular Physics Quizzes

(2000-01 School Year)

 

Suggestions for this week's quiz (Unit 11 Quiz):

This week's quiz on Unit 11 material is tentatively scheduled for Friday, March 8. The quiz will be a short one-page quiz (maybe more), covering both sides of a single sheet of paper. The equations for the speed of a wave and the frequency-period relationship 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 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.
  4. An understanding of the concepts of natural frequency, forced vibration, and resonance; an ability to relate the resonance mode (or harmonic) of a guitar string 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.
  5. An ability to use the v = f*lambda equation, a standing wave diagram, and the length-wavelength relationship to solve computational problems involving stringed instruments
  6. 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. See the Multimedia Physics Studios.
  7. An understanding of previous wave concepts from Unit 10. Use the link below to see the Studying Suggestions for the Unit 10 quizzes.
