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? A) z(z,t)= +4.0 cm cos(1,200 rad/s t)cos(20 m^-1 z). B) z(z,t)= +4.0 cm cos(1,200 rad/s t)sin(20 m^-1 z) C) z(z,t)= +4.0 cm cos(1,200 rad/s t)cos(20 m^-1 z) D) z(z,t)= -2.0 cm cos(1,200 rad/s t)sin(20 m^-1 z)
