web.pa.msu.edu1. When a sine wave is used to represent a sound wave, the crest corresponds to: a. rarefaction b. condensation c. point where molecules vibrate at a right angle to the direction of wave travel d. region of low elasticity 2. A sound wave coming from a tuba has a wavelength of 1.50 m and travels to your ears at a speed of 345 m/s.

amath.colorado.eduThe simplest model of a musical sound is a sine wave, were the domain (x-axis) is time and the range (y-axis) is pressure. P Asin(2 ft) where: P pressure, in decibels or Pascals t time, in seconds A amplitude (height of the wave) or volume, in decibels or Pascals f frequency or pitch, in hertz. T period, in seconds is the duration of one wave ...
