Properties of Waves: Amplitude, Wavelength, Frequency and Speed

1. A wave is a disturbance involving the transfer of energy from place to place.

   • Amplitude
     • The amplitude is the maximum distance the medium vibrates from the 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 called the wavelength. The 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 measured in units called hertz (Hz), and is defined as the number of waves per second.
   • Speed
     • The speed of a wave is how far the wave travels in a given amount of time. Different waves travel at different speeds. You can determinate the speed of a wave by dividing the distance it travels by the time it takes to travel the distance.
