As a certain sound wave travels through the air, it produces pressure variations (above and below atmo- spheric pressure) given by AP = 1.27 sin (7x - 340t) in SI units. Find (a) the amplitude of the pressure vari- ations, (b) the frequency, (c) the wavelength in air, and (d) the speed of the sound wave.
