  5. What do waves transfer from one location to another?
    energy
  6. Which of the following best describes sound waves?
    A. a series of compressions and rarefactions
    B. movement of molecules and energy from one location to another
    C. waves that are used to make images of anatomy
    D. waves that are heard by man

    (this multiple choice question has been scrambled)
  8. Variations in all of the following identify specific waves as acoustic waves except:
    A. pressure
    B. parameters
    C. density
    D. acoustic variables
    B.
  9. All of the following are true of sound waves except:
    A. they are acoustic
    B. they are pressure waves
    C. they are transverse
    D. they move energy
    • B.
    • Sound waves are longitudinal, not transverse

    A. pressure
    B. period
    C. propagation speed
    D. frequency
    • A.
    • pressure is an acoustic variable, not parameter.
