You are watching: What is the highest point of a wave
Graphing a WaveWhen illustration a tide or looking in ~ a wave on a graph, we attract the wave as a snapshot in time. The upright axis is the amplitude of the wave while the horizontal axis can be either street or time.
In this picture you have the right to see the the highest point on the graph that the wave is dubbed the crest and also the lowest allude is referred to as the trough. The line through the facility of the tide is the resting position of the medium if there to be no wave passing through.We can determine a variety of wave nature from the graph.AmplitudeThe amplitude the a wave is a measure up of the displacement of the wave from its rest position. The amplitude is presented on the graph below.
Amplitude is usually calculated by spring on a graph of a wave and also measuring the height of the tide from the relaxing position.The amplitude is a measure of the stamin or strongness of the wave. Because that example, when looking in ~ a sound wave, the amplitude will certainly measure the loudness the the sound. The power of the wave additionally varies in straight proportion come the amplitude that the wave.WavelengthThe wavelength the a wave is the distance in between two matching points ~ above back-to-back cycles the a wave. This have the right to be measured between two crests the a tide or two troughs the a wave. The wavelength is usually stood for in physics by the Greek letter lambda (λ).
Frequency and PeriodThe frequency that a tide is the number of times per 2nd that the wave cycles. Frequency is measure up in Hertz or cycles every second. The frequency is frequently represented by the lower instance "f."The duration of the tide is the time in between wave crests. The period is measured over time units such together seconds. The period is usually stood for by the upper situation "T."The duration and frequency are very closely related to each other. The period equals 1 over the frequency and the frequency is equal to one over the period. They room reciprocals that each other as presented in the following formulas.

Speed or Velocity the a WaveAnother essential property that a tide is the speed of propagation. This is how rapid the disturbance that the tide is moving. The speed of mechanically waves depends on the tool that the wave is traveling through. For example, sound will travel at a different speed in water than in air.The velocity of a tide is usually represented by the letter "v." The velocity have the right to be calculation by multiply the frequency by the wavelength.
