Sound Wave The oscillations in air pressure representing the sound wave for a tone at thestandard pitch of A can be modeled by the equation y = 0.02 sin (880pt), where y is thesound pressure in pascals after t seconds. Sketch the graph of this function for 0 <= t <= 0.01. Frequency With simple harmonic motion, the reciprocal of the period is called the fre-quency. The frequency, given by f = 1/periodrepresents the number of cycles (or oscillations) that are completed per unit time. The unitsused to describe frequency are Hertz, where 1 Hz = 1 cycle per second.
