A longitudinal wave is represented by the equation z(z, t) = −2.0 cm sin(1,200 rad/s t − 20 m−1 z). Another longitudinal wave is represented by the equation z(z, t) = +2.0 cm sin(1,200 rad/s t + 20 m−1 z). What is the equation that represents the superposition of the two waves?



z(z, t) = -4.0 cm cos(1,200 rad/s t) sin(20 m−1 z)



z(z, t) = +4.0 cm cos(1,200 rad/s t) sin(20 m−1 z)



z(z, t) = +4.0 cm cos(1,200 rad/s t) cos(20 m−1 z)



z(z, t) = −2.0 cm cos(1,200 rad/s t) sin(20 m−1 z)
