Stationary waves are formed in an acoustic medium by combining two simple harmonic waves in such a way that the point x = 0 is a node. The equation of one of the waves is y = a cos (ωt − kx). The equation of the other wave is (1) y = a cos (ωt + kx) (2) y = a sin (ωt + kx) (3) y = − a cos (ωt + kx) (4) y = − a sin (ωt − kx) |
