Essay on Acoustic Waves in Physics - 682 Words

Acoustic Waves in Physics  An acoustic wave can simply be described as a longitudinal wave. A longitudinal wave is a wave that vibrates and moves in the direction of its propagation. This means the medium is either in the same or opposite direction of the way the wave travels. Acoustic waves are a form of Mechanical longitudinal waves; these waves are otherwise known as compression waves or compressional waves. Compressional waves obviously produce compression, decompression, and rarefaction to travel. In Physics, the acoustic wave has an equation to describe the evolution of acoustic pressure and particle velocity as a function. The general equation is: Acoustic waves have multiple equations, but this version is the†¦show more content†¦The molecules seem to move when something pushes them and forces the molecules to bump into each other. This process makes the compression and rare factor that I have talked about before. Acoustic waves are an isolation of pressure that travel in a wave pattern. Acoustic waves cause a vibration that leads to your ear that allows us to hear. These acoustic waves are defined by three different characteristics. These characteristics are amplitude, frequency and wave length. Amplitude is the energy in a wave. The amplitude affects its volume or sound. The number of waves that pass a point at each second, the higher the frequency, the higher the pitch compared to those who have low frequencies. You can describe these waves as the waves that allow humans and other species to hear. There is not different types of acoustic waves. The acoustic wave is a longitudinal compressional wave. [8] There are no other kind of acoustic waves, sometimes they have different equations but that is because some are higher and or stronger than others. Acoustic waves in fact can be reflected. It is said that the waves can possibly exhibit different sorts of phenomena. Diffraction, interference and reflection are all examples of phenomena the wave can go through. This brings to topic an important difference between acoustic waves and sound waves. Without acoustic waves it would beShow MoreRelatedThe Physics of Acoustic Guitar800 Words   |  4 Pages The Physics of Acoustic Guitar Everything in the universe involves some type of physics. Even the universe itself does, but have you ever wondered about the physics of simpler items? Physics is vital for all musical instruments, if it wasn’t; they probably wouldn’t produce the beautiful sounds that they do. One of these instruments is acoustic guitar. By looking at the instrument, it doesn’t look very complicated, but if you delve deeper into its composition, you’ll find that it’s very complicatedRead More The Physics of Ultrasounds Essay1717 Words   |  7 PagesThe Physics of Ultrasounds Without the use of physics in the medical field today, diagnosis of problems would be challenging, to say the least. The world of medical imaging in particular has benefited greatly from the use of physics. Ultrasound is sound waves that have a frequency too high for humans to hear. With a shorter wavelength than audible sound, these waves can be directed into a narrow beam that is used in imaging soft tissues (Farr and Allisy-Roberts 183). As with audibleRead More81253894 Ultrasound Physics Essay1171 Words   |  5 Pagesï » ¿ ULTRASOUND PHYSICS Name Institution a) Calculate the Acoustic impedance of subcutaneous tissue, muscle and bone.

So the acoustic pressure is close to zero. In order for a wave to satisfy this condition the longest standing wave is one in which its wavelength is twice as long as the flute! The pressure inside the tube does not have to be atmospheric.

Physics allows us to create musical instruments with different tone qualities and the ability to be played in a certain way to produce a specific pitch or note. Music is sound, and sound is vibrations or waves that are at the right frequency to be perceived by the human ear. Audible vibrations are waves with a frequency between 16 and 20,000 vibrations per second. So what causes sound waves?
