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.
Part (a): The wave's amplitude, wavelength, and frequency can be determined from the equation of the wave: y(x,t) = (0.9 cm) sin[(1.2 m -1)x - (5.0 s -1)t]. The amplitude is whatever is multiplying the sine.A = 0.9 cm. The wavenumber k is whatever is multiplying the x:et's say that for a particular wave on a string the equation is: y(x,t) = (0.9 cm) sin[(1.2 m -1)x - (5.0 s -1)t]. (a) Determine the wave's amplitude, wavelength, and frequency. (b) Determine the speed of the wave. (c) If the string has a mass/unit length of m = 0.012 kg/m, determine the tension in the string.
