What is a mechanical wave?
The mechanical wave is an interference that pulsates in some form of the medium: solid, liquid or gas, carrying the original initiation of energy from one place to another. There are three types of mechanical waves: transverse, longitudinal and boundaries. The simple examples of waves and media they move are sound in the air, seismic waves in the rock and the vibration of the guitar chain.
One example of mechanical waves is the waves in the pond that moves out, where the stone is dropped. The wave moves through the medium, although the atoms and molecules of the media themselves generally return to their original position after being compressed together, stretched or rotated through the wave passing through them. The mechanical wave can move by direct movement, rotary movement or a combination of these two.
Waves have frequency, periods, wavelengths and amplitude. The distance between one wave pulse and the other wavelength and the time between the pulses is the period. For transverse waves, the amplitude is the distance that the wave is pushed by the medium. InitialET waves passing through the medium over time is the frequency of wool. The higher the frequency of the mechanical wave, the greater the energy it transmits.
transverse waves transmit their energy up and down or side-on side, forcing the medium to take the form of the ridge and the trough-as in the sinus wave. A good example of this kind of wave is the seismic wave of S, in which the Earth's crust moves up and down, or to the side, perpendicular to the direction of the wave spread. The mechanical wave model of the transverse wave is given by a wave equation, an energy equation, which is a solution of a sinus wave, which has the above characteristics of frequency, period, wavelength and amplitude.
Longitudinal waves are waves of density that move expansion and compression of the media particles. One expansion and compression is one wavelength. Good examples of these waves are the sound waves in the air and seismic p-wavy in the ground. The greater the density of the material, the fastMore waves move through it.
Border waves are mechanical waves that resonate between two different media. Air cavities and limited strings in musical instruments, vibrations of tuning fork and crown shape with droplet droplet are a good example of mechanical waves. The resonant sound of the tuning fork is limited by the shape and size of its boundaries and elasticity of the material that composes it.
