Sound and Wave CLUES!!!

  1. Know all definitions (boldfaced words and terms from class discussion) and know them well...
  2. Know how all discussed concepts apply to the "Sound Circus" stations.
  3. v = f l  Know how to use and apply this equation to questions, such as:
  4. What happens to the frequency of the wave if you double the speed of the wave? Answer this question in terms of the v = f l  equation and then provide an explanation, with a drawing that demonstrates what happens to the waves’ speed. In other words, relate your mathematical answer to a conceptual answer.

  5. Know and explain the differences AND similarities between transverse and longitudinal/compressional waves.

Consider these concepts:

  1. What exactly is frequency, and how is it measured? What are its units?
  2. How is frequency different form wave speed?
  3. Explain the Doppler effect: What do you hear/see? Why? (Explain which characteristics of the sound waves (v, f, l & A) are being changed versus which characteristics are not and how these relate to what happens.) 
  4. What is the Principle of Linear Superposition?  What can this cause?
  5. What is a standing wave? What are its parts? How are they formed? Why are they important? What is the meaning of life, the universe, and everything?
  6. What is resonance? Why & when does it happen? What characteristic of waves effects whether resonance occurs or does not occur? 
  7. What causes constructive interference? What causes destructive interference? What are the results? What do we call it?
  8. How are sounds amplified? How & why does a megaphone work?
  9. How do we hear?  
  10. Consider how sound acts like a wave. What effect does each of these wave characteristics have on what you actually hear:…?

…..Medium of travel
…..if the wavelength is increased, but the speed stays the same, what do you hear?
…..What phenomenon is related to last question?
