Sound and Wave CLUES!!!
- Know all definitions (boldfaced words and terms from class discussion) and
know them well...
- Know how all discussed concepts apply to the "Sound
- v = f l
Know how to use and apply this
equation to questions, such as:
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.
- Know and explain the differences AND similarities between transverse and
Consider these concepts:
- How do you find the wavelength for each of the 2 types of waves?
- How do you find the amplitude for each of the 2 types of waves?
- Describe the way energy travels in each of the types of waves.
- How do you determine the frequency for each of the types of waves?
- What exactly is frequency, and how is it measured? What are its units?
- How is frequency different form wave speed?
- Explain the Doppler effect: What do you hear/see? Why? (Explain which
characteristics of the sound waves (v,
f, l &
are being changed versus which
characteristics are not and how these relate to what happens.)
- What is the Principle of Linear Superposition?
What can this cause?
- 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
- What is resonance? Why & when does it happen? What characteristic of
waves effects whether resonance occurs or does not occur?
- What causes constructive interference? What causes destructive
interference? What are the results? What do we call it?
- How are sounds amplified? How & why does a megaphone work?
- How do we hear?
- 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
…..What phenomenon is related to last question?
- Study your notes, lab observations & sections 8.1-8.3 in your book.

content – but it may help…) check the "Physics
