Sound Wave Diagram Explained. As we stated previously sound is a mechanical wave. The motion of the particles is parallel and anti parallel to the direction of the energy transport.
There are loud sounds and quiet sounds high pitched squeaks and low pitched rumbles and even two instruments playing exactly the same musical note will produce sound waves that are quite different. Using sound to navigate flying at the speed of sound when a plane travels at the speed of sound sound waves pile up in front of it. This distance is known as the wavelength of the sound usually measured in metres and represented by λ.
Using sound to navigate underwater echoes are used by ships to scan the ocean floor.
The low pressure areas are represented as troughs of the graph. There are loud sounds and quiet sounds high pitched squeaks and low pitched rumbles and even two instruments playing exactly the same musical note will produce sound waves that are quite different. The high pressure areas are represented as the peaks of the graph. The waveform representation converts the pressure variations of sound waves into a pictorial graph which is easier to understand.
