Stocking rates are expressed as the number of animal unit months (AUM) supplied by one acre of land. The greater the difference between current forage production and the potential forage production of a pasture, the greater the difference will be between carrying capacity and recommended stocking rate.
The fundamental frequency of a wave is the lowest frequency (longest wavelength) that can be used to define its period. The easiest way to understand it is via a musical analogy: The fundamental frequency is the root tone of the overtone or harmonic series.
The frequency of the periodic motion is known as a vibration frequency, and the typical frequencies of molecular vibrations range from less than 10 12 to approximately 10 14 Hz. fundamental vibration is excited when one such quantum of energy is absorbed by the molecule in its ground state. When two quanta are absorbed the first overtone is excited, and so on to higher overtones. To a first approximation, the motion in a normal vibration can be described as a kind of simple harmonic motion.
