Maddox (given name) Maddox is a mainly male name in use in English speaking countries derived from a Welsh surname meaning son of Madoc.. Madoc or Madog was a legendary Welsh prince who in Welsh folklore sailed to the New World three hundred years before Christopher Columbus. The name means fortunate and is derived from the Welsh word mad.
The energy transported by a wave is directly proportional to the square of the amplitude of the wave. This energy-amplitude relationship is sometimes expressed in the following manner. This means that a doubling of the amplitude of a wave is indicative of a quadrupling of the energy transported by the wave.
Waves carry energy, and the amplitude of a wave is generally a measure of how much energy the wave carries. In the same way, the displacement of a bow string, determines the amount of energy that propels the arrow. Energy is a positive quantity, so the amplitude is a positive number. However... Scientists don't usually talk about the amplitude of a light wave, since light isn't traveling in some substance like water or air.
