Question
The propagation of sound waves can be graphically represented by plotting _____ against _____.
- Density, time
- Pressure, time
- Density or pressure, time
- Density or pressure, distance
Hint:
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.
