   • Amplitude
     • The amplitude is the maximum distance the medium vibrates from its rest position. Amplitude describes how far the medium in a wave moves
   • Wavelength
     • A wave travels certain distance before it starts to repeat. The distance between two corresponding parts of a wave is the wavelength.Wavelength describes the wave`s length.
   • Frequency
     • The frequency is the number of waves that pass a given point in a certain amount of time. Frequency is measure in units called hertz (Hz), and is defined as the number of waves per second
   • Speed
