Question

The propagation of sound waves can be graphically represented by plotting _____ against _____.

  1. Density, time
  2. Pressure, time
  3. Density or pressure, time
  4. Density or pressure, distance

hintHint:

The propagation of sound waves can be graphically represented by plotting density or pressure against the distance.

The correct answer is: Density or pressure, distance


    • The sound propagates through a compressive media of particular density.
    • The sound waves can be reflected, refracted, or attenuated by the medium.
    • Its graphical representation can be done by plotting the density of medium or pressure of the sound against the distance.
