TRANSVERSAL WAVE
A wave can be grouped into trasnversal wave if the particles of the medium vibrate upwards and downwards in the direction perpendicular to the wave motion. Examples of transverse waves are waves of string. When our move the rope up and down, it appears that the rope moves up and down in the direction perpendicular to the direction of wave motion. Transverse wave form look like the picture below.
Based on the picture on the side, it appears that the waves propagate to the right in the horizontal plane, while the vibration direction up and down in a vertical plane. The dotted lines drawn in the middle along the direction of wave propagation state equilibrium position of the medium (eg a rope or water). The highest point is called the wave peak, while the lowest point is called the valley. Peak amplitude is the maximum height or maximum depth of the valley, measured from the equilibrium position. Distance from the same two points and a sequence of wave is called wavelength (called lambda - greek letters). Wave lengths can also be also considered as the distance from peak to peak or from valley to valley distance.
