The wavelength of a wave is the distance over which the wave's shape repeats itself
An example of this is shown with the sine wave
The top of the wave is called the crest and the bottom is called the trough
The SI unit of wavelength is the meter.
We can find the wavelength of a sound wave from the equation λ =\(\frac{v}{f}\)
The amplitude of a wave is the change over a period
The amplitude effects the loudness of the tone of the sound
The amplitude is not always constant with sound waves
