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.
Frequency, wavelength, amplitude and wave speed. You need to know about these quantities used in waves - what they mean, the symbols used for them and the units used to measure them. The amplitude, a, of a wave is the distance from the centre line (or the still position) to the top of a crest or to the bottom of a trough. Be careful with this quantity - the centre line is not always given in a diagram. Amplitude is measured in metres (m). The greater the amplitude of a wave then the more energy it is carrying. The wavelength, Î», of a wave is the distance from any point on one wave to the same point on the next wave along.
