Waves have many different properties
The frequency of a wave is the number of cycles per unit time
The frequency of a wave is inversely proportional to its period, T =\(\frac{1}{f}\)
The wavelength of a wave is the distance over which the wave's shape repeats itself, and has the symbol λ
The top of the wave is called the crest and the bottom is called the trough
We can relate all of these properties using the equation λ =\(\frac{v}{f}\)
The amplitude of a wave is the change over a period
Generally in questions, you will not use the peak-to-peak amplitude
