2.0 Introduction
Sound is produced when something vibrates. The vibrating object causes the atoms in the atmosphere to also vibrate the medium be that water, air or gas. There are two types of sound waves, transvers and Longitudinal. In a transverse wave the particle displacement is perpendicular to the direction of wave’s motion. The particles that act as a medium have no horizontal movement as the transverse wave passes; they simply oscillate vertically about their individual equilibrium positions as the wave passes by. In a longitudinal wave the particle displacement is in the same direction to the motion of the wave. The particles do not move down the tube with the wave; they simply oscillate back and…show more content… This causes a Longitudinal wave to be produced causing sound, the pitch of a guitar can be changed by changing the linear density of the string, changing the tension and changing the temperature. When a sting vibrates it does not move many particles around it because of its small surface area. Because of this fact something is needed to help amplify the area of particles it vibrates. This is where the ‘box’ of a guitar comes; the guitar string forces the box to vibrating at the same frequency as the string. Because the box beings to vibrate the surface area of particles that is vibrating increases amplifying the sound the guitar string makes, helping to make the sound more audible.
Waves in a string are transverse waves, where the string is pulled and released causing it to vibrate. As explain earlier there is no movement at the nodes but in-between them there is large amounts of movement, Also known as anti-nots the place with the furthers displacement from equilibrium. The standing waves of air in a tube are not transverse waves. Like all sound waves, they are longitudinal. For example when wind is pushed through a instrument the vibrations in the medium are flowing in the same
