Web21 jun. 2024 · Sound and vision . Before we talk about infrasound, or any sound, it's probably useful to discuss just exactly how the sense works. According to Scientific American, sound can be defined as "pressure waves that oscillate, or alternate, between compressing and stretching the matter they travel through (in our case, air) at a certain … WebSound moves through a medium such as air or water as waves. It is measured in terms of frequency and amplitude. Frequency, sometimes referred to as pitch, is the number of times per second that a sound pressure wave repeats itself. A drum beat has a much lower frequency than a whistle, and a bullfrog call has a lower frequency than a cricket.

WebWhen a wave passes through a denser medium, it goes faster than it does through a less-dense medium. This means that sound travels faster through water than through air, and faster through bone than through water. When molecules in a medium vibrate, they can move back and forth or up and down. WebSound waves traveling through air are indeed longitudinal waves with compressions and rarefactions. As sound passes through air (or any fluid medium), the particles of air do …

Web17 jan. 2024 · Sound waves basically travel by vibrating the particles in a medium, i.e., molecules of air. These vibrations are passed on to consecutive particles in the medium, meaning that sound waves cannot travel without a medium.
