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.
What does it mean? 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.nergy is a positive quantity, so the amplitude is a positive number.
