Given information
A sound wave is the pattern of a disturbance generated by the flow of energy as it propagates away from the source of the sound across a medium (such as air, water, or any other liquid or solid substance). A source is a vibration-producing object, such as a ringing phone or a person's vocal cords. The vibration affects the particles in the surrounding medium, which disturb the particles adjacent to them, and so forth. Like waves of saltwater on the ocean, the pattern of the disturbance causes outward movement in a wave pattern. The sound energy is carried by the wave through the medium, usually in all directions and less intense as it moves away from the source.
Step-by-step explanation
Longitudinal Sound Waves:
A longitudinal wave occurs when the velocity of the medium's particles is parallel to the energy transfer direction. The coils of a slinky move in a parallel direction when you push it back and forth (back and forth). Similarly, when a tuning fork is hit, the sound wave travels in the same direction as the air particles.
Mechanical Sound Waves :
In a chain reaction, a sound wave passes through air by displacing air particles. When one particle moves away from its equilibrium position, it pushes or pulls on other molecules, forcing them to move away from their equilibrium as well. The disturbance is spread throughout the medium as particles continue to displace one another with mechanical vibrations. Sound waves are classified as mechanical waves because of the particle-to-particle mechanical vibrations of sound conductivity. Sound energy, or energy linked with the vibrations made by a vibrating source, must flow through a medium, making it a mechanical wave.
