Lessons. Medium. Mechanical waves are waves that require a medium in order to transport their energy from one location to another. Transverse Wave. Mechanical Waves and Sound . 03:46. As the particles continue to push against each other, the sound wave travels through the air. the highest point of a wave above the resting point. Examples of mechanical waves include ripples on the water surface (water waves), sound waves, and Material through which a wave travels. For now, we'll focus on mechanical waves, requiring a medium in which to travel. For each type of wave, compare the vibration of the medium to the direction of the wave. In a surface wave, the particles vibrate both up and down and from side to side, so they end up going around in a circle. In human physiology and psychology, sound is the reception of such waves and their perception by the brain. via the mechanism of particle-to-particle interaction, a sound wave is characterized as a mechanical wave..

Speed of sound in air – About 340 m/sec → varies strongly with temperature Sound waves coming from a tuning fork are caused by the vibrations of the tuning fork which push against the air particles in front of it. Sound cannot travel through a region of space that is void of matter (i.e., a vacuum). Simple harmonic motion. Mechanical waves can propagate through solid, liquid, or gas. Before sharing sensitive information, make sure you're on a federal government site. The particles behind the compression move further apart causing a rarefaction. What is reflection . vibration that propagates through a medium in the form of a mechanical wave The particles appear to be moving through but they are simply being displaced which then creates a wave.
