A transverse periodic wave is represented by the equation y(z, t) = 2.0 cm sin(1,200 rad/s t - 20.0z). Another transverse wave is represented by the equation y(z, t) = 2.0 cm sin(1,200 rad/s t - 20.0z). What is the equation that represents the superposition of the two waves?

A. y(z, t) = 4.0 cm sin(1,200 rad/s t - 20.0z)

B. y(x, t) = 4.0 cm sin(1,200 rad/s t) cos20.0x)

C. y(x, t) = +4.0 cm cos(1,200 rad/s) sin(20.0 x)

D. y(x, t) = +4.0 cm cos(1,200 rad/s) + (20.0x)


A. y(z, t) = 4.0 cm sin(1,200 rad/s t - 20.0z)
