Question:

As a certain sound wave travels through the air, it produces pressure variations (above and below atmospheric pressure) given by ΔP = 1.27 sin (πx ─ 340πt) in SI units. Find
(a) The amplitude of the pressure variations,
(b) The frequency,
(c) The wavelength in air, and
(d) The speed of the sound wave.
