Properties of waves


Every wave has a property to it. Without properties, the waves wouldn't behave in certain ways and some of the properties allow us to measure different components of the wave. With out these factors, the information we know about waves would not be available to us today.

Properties


There are many different properties to each wave but the main properties are amplitude, wavelength, crest, trough, period, frequency and oscillation. Each property is explained below.

Amplitude


Amplitude is is the measurement of a wave's height as it also measures the oscillation of the wave to get the height. For example, when the amplitude of a sound wave is measured, it depends on the vibration and pitch of the source transferring the waves. The higher the pitch, the higher the amplitude.

Wavelength


Wavelength is the measurement of a wave's distance it travels and repeats it's self. This is measured by certain points of the wave such as the crests or the trough's. This is a general properties as its one of the main ones in any wave.

Crest


A crest is a certain point in a wave. Its the opposite of a trough as the crest is always located in highest point of a wave. Crests can be used to measure the wavelength of a wave.

Trough


Like a crest, a trough is a certain point in a wave. The trough is located in the lowest point of the crest and like the crest, it can be used to measure the wavelength of a wave.

Period


Period is the amount of time an event takes to occur. A simple example of a period is the amount of time school days occur, 5 days is the period of school days that pass in a week. This can be used with waves when measuring the period of time a wave occurs.

Frequency


Frequency is the amount of times a certain thing occurs. Frequency can be used on waves to discover how much they occur in a period of time. They can also be used to discover many other things such as colour of a light wave and the pitch of a sound wave.

Oscillation


Oscillation is the event of something repeating itself over again. An example of oscillation is a swing seat swinging. Oscillation is used in wave terms to describe that waves can repeat over again. Oscillation can be used to discover the frequency of a wave as the frequency will use oscillation to find out how many times a wave will occur as waves repeat its self.

Equations


To get certain answers, equations must be used. Properties of waves are used as factors in certain equations. Listed below are some equations that involve wave properties to get the answer.

Wave speed


To discover the wave speed of a wave the equation listed below must be followed:
Wave Speed=Distance and frequency

Wave Length


To discover the wavelength of a wave the equation below must be followed:
Wave Length=a100432cfbaa6417ffccfab51609f53b.png
This is basically velocity and frequency to get the wavelength.

Relationship between waves and energy


The relationship between waves and energy is that energy produce waves. An example of energy producing waves is a speaker with sound carrying energy therefore producing sound waves. Without energy, waves wouldn't be able to produce. So in a way, energy acts like the foundation of a wave.
