If you or a blood relative have had a problem related to anesthesia or surgery, please let your anesthesiologist know. A thorough medical history and physical exam is, of course the most important information your anesthesiologist can receive.
Points C and J on the diagram represent the troughs of this wave. The trough of a wave is the point on the medium that exhibits the maximum amount of negative or downward displacement from the rest position. The wave shown above can be described by a variety of properties. One such property is amplitude. The amplitude of a wave refers to the maximum amount of displacement of a particle on the medium from its rest position. In a sense, the amplitude is the distance from rest to crest. Similarly, the amplitude can be measured from the rest position to the trough position.
When the amplitude of a wave is proportional to the waveâs energy, the intensity of the wave (that is, the power transmitted by the wave per unit area) is proportional to the square of its amplitude. When we describe simple harmonic motion, amplitude refers to the maximum displacement of the oscillating object from the equilibrium position.
