Two acoustical waves are incident on one point after traversing different paths. The two waves are characterized by the following amplitude variations

p1=0.5sin( 2πx1-684πt )Pa,

p2=0.5sin( 2πx2-684πt+α )Pa,

Derive an expression for the resultant pressure.
What is the frequency and wavelength of these two waves?
For t=2.924 ms, what are the resultant amplitudes for x1=x2=1 m, for α=0, α=4, and α=π/2 radians?
For t=2.924 ms, what are the resultant amplitudes when x1=1.25 m and x2=1 m, for α=0, α=π/4, and α=π/2 radians?
