WebThis energy travels in the form of waves, which are called sound waves. A sound wave consists of vibrations of particles of the medium through which it travels. If there is no medium, the vibrations from an object will not travel through it. The source of sound always produces some kind of vibrations. These sound waves travel in the air as ... WebA wave is a disturbance that travels or propagates from the place where it was created. Waves transfer energy from one place to another, but they do not necessarily transfer …

How do you transform sound into radio waves? : askscience

WebInterestingly enough, decibels (dB) are a measure of sound pressure. As the wave propagates, there are high amplitudes of the wave (which correspond to the air compressing and having higher density) and low amplitudes of the wave (which corresponds to the opposite effect). WebWhat Is Sound. In physiology, sound is produced when an object’s vibrations move through a medium until they enter the human eardrum. In physics, sound is produced in the form of a pressure wave. When an object vibrates, it causes the surrounding air molecules to vibrate, initiating a chain reaction of sound wave vibrations throughout the medium. crg medical editing

Web1 day ago · No, sound waves can not be polarised in gas and liquid media. It is because sound waves, in gas and liquid medium, oscillate parallel and not perpendicular to the direction of their motion. The property of polarisation is only exhibited by transverse waves that move up and down or side by side i.e., perpendicular to the direction of propagation.
