Does this graph is correct representing a sound wave?

  1. Jan 30, 2008 #1
    I had today an exam.

    I that exam this graph they said represent a sound wave. Is this graph correct representing a sound wave in a medium? My interrogation is about y/m as a function of x/m!

    No help! Is this a nonsense question?

    well, i guess no, it's not right, as sound waves are compressive waves, not like electromagnetic that look like that(or more or less like that).

    It looks like a sine wave to me. So y/m=Asin(kx/m). Find A and k to reproduce the peaks and zeros of the wave.
