Graphing a WaveWhen illustration a tide or looking at a wave on a graph, we attract the wave as a photo in time. The vertical axis is the amplitude of the wave while the horizontal axis can be either distance or time.
In this picture you have the right to see the the highest suggest on the graph that the wave is called the crest and the lowest allude is referred to as the trough. The line v the center of the wave is the resting position of the tool if there to be no tide passing through.We have the right to determine a variety of wave nature from the graph.AmplitudeThe amplitude the a wave is a measure of the displacement the the wave from its rest position. The amplitude is shown on the graph below.
Amplitude is usually calculated by looking on a graph that a wave and also measuring the height of the wave from the relaxing position.The amplitude is a measure of the toughness or intensity of the wave. For example, as soon as looking in ~ a sound wave, the amplitude will certainly measure the loudness of the sound. The power of the wave additionally varies in straight proportion come the amplitude the the wave.WavelengthThe wavelength that a wave is the distance between two matching points top top back-to-back cycles of a wave. This have the right to be measured in between two crests that a wave or 2 troughs the a wave. The wavelength is usually stood for in physics by the Greek letter lambda (λ).
Frequency and also PeriodThe frequency that a wave is the variety of times per second that the wave cycles. Frequency is measured in Hertz or cycles every second. The frequency is often represented through the lower case "f."The duration of the tide is the time between wave crests. The duration is measured in time units such as seconds. The duration is usually stood for by the upper instance "T."The period and frequency are very closely related to each other. The period equals 1 over the frequency and also the frequency is equal to one end the period. They room reciprocals of each various other as presented in the following formulas.

Speed or Velocity of a WaveAnother vital property the a tide is the rate of propagation. This is how rapid the disturbance that the wave is moving. The speed of mechanical waves relies on the tool that the tide is traveling through. Because that example, sound will travel at a different speed in water than in air.The velocity that a wave is usually stood for by the letter "v." The velocity deserve to be calculate by multiply the frequency by the wavelength.
