Properties of Waves

Properties of Waves

1. Amplitude

   • Amplitude is the maximum distance the medium vibrates from the rest position. Amplitude describes how far the medium in wave moves.High waves have more energy than low waves. The more energy a wave has, the greater its amplitude

2. Wavelength

   • The distance between tow corresponding parts of a wave. Wavelength describes a wave length.

3. Frequency

   • The frequency of wave is the number of waves than pass a given point in certain amount of time. Frequency is measured in units called hertz,and is defined as the number of waves per second. A wave that occurs every second has frequency of 1 wave per second. If two waves pass every second the frequency is 2 waves per second

4. Speed

   • Different waves travel at different speeds. Think about watching a distant thunderstorm on a hot summer day. This happens because light waves travel much faster than sound waves. The speed of wave is how far the wave travels in given amount of time

5. How are Frequency, Wavelength, and Speed Related?

   • The speed, wavelength,and frequency of a wave are related by a mathematical formmula.
     • Speed = Wavelength x Frequency Frequency = Speed ÷ Wavelength Wavelength = Speed ÷ Frequency
