Sound Wave Diagram Explained. As we stated previously sound is a mechanical wave. It is created by a vibrating motion that travels through a conductive non vacuous medium.
They travel through a medium by making atoms or molecules shake back and forth. The low pressure areas are represented as troughs of the graph. The second trait helps to explain why sound a mechanical wave does not transmit when sent through tunnels underwater and all other examples of vacuous structures.
They travel through a medium by making atoms or molecules shake back and forth.
The waveform representation converts the pressure variations of sound waves into a pictorial graph which is easier to understand. The shaded bar above it represents the varying pressure of the wave. A sound wave is made of areas of high pressure alternated by an area of low pressure. The waveform representation converts the pressure variations of sound waves into a pictorial graph which is easier to understand.
