1.1A 2 kHz sound wave traveling in the x direction in air was observed to have a differential pressure p(x, t) = 10 N/m2 at x = 0 and t = 50 μs. If the reference phase of p(x, t) is 36◦, find a complete expression for p(x, t). The velocity of sound in air is 330 m/s. 1.2 For the pressure wave described in Example 1-1, plot the following: (a) p(x, t) versus x at t = 0 (b) p(x, t) versus t at x = 0 Be sure to use appropriate scales for x and t so that each of your plots covers at least two cycles.
