Question

Two sound waves, ∆P1 and ∆P2, have the same wavelength and are traveling along a pipe with speed 343 m/s. The superposition is a standing wave. ∆P1 = (1.4 Pa) sin (kx − ωt) and ∆P2 = (1.4 Pa) sin (kx + ωt + π/4). Their wave numbers are both k = 2π rad/2.2 m. What is the distance between the nodes? (a) 1.1 m (b) 4.4 m (c) 0.55 m (d) 2.2 m
