Sound - Wikipedia In physics, sound is a vibration that propagates as an acoustic wave through a transmission medium such as a gas, liquid or solid In human physiology and psychology, sound is the reception of such waves and their perception by the brain [1]
Sound | Properties, Types, Facts | Britannica Sound propagates through air or other mediums as a longitudinal wave, in which the mechanical vibration constituting the wave occurs along the direction of propagation of the wave
The Science of Sound - NASA Sound waves are longitudinal waves that travel through a medium like air or water When we think about sound, we often think about how loud it is (amplitude, or intensity) and its pitch (frequency) What is sound? What are the parts of a sound wave?
What is a sound wave, and what do sound waves move or travel . . . What is a sound wave? A sound wave is the pattern of disturbance caused by the movement of energy traveling through a medium (such as air, water or any other liquid or solid matter) as it propagates away from the source of the sound Sound waves are created by object vibrations and produce pressure waves, for example
Understanding Sound Waves and How They Work - HowStuffWorks Sound waves are fundamentally pressure waves, traveling through the compression and rarefaction of particles within a medium Sound waves consist of areas where particles are bunched together, followed by areas where they're spread apart
Sound - The science of waves, how they travel, how we use them Top: Sound waves are longitudinal waves: the air moves back and forth along the same line as the wave travels, making alternate patterns of compressions and rarefactions Bottom: Ocean waves are transverse waves: the water moves back and forth at right angles to the line in which the wave travels
