A Transverse Periodic Wave Is Represented by the Equation Y(z,t)

question 17

Multiple Choice

A transverse periodic wave is represented by the equation y(z,t) = 2.0 cm sin(1,200 rad/s t - 20.0 m^-1 z) .Another transverse wave is represented by the equation y(z,t) = 2.0 cm sin(1,200 rad/s t - 20.0 m^-1 z) .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 - 20.0 m^-1 z)
• B) y(x,t)= 4.0 cm sin(1,200 rad/s t)cos20.0 m^-1 x)
• C) y(x,t)= +4.0 cm cos(1,200 rad/s)sin(20.0 m^-1 x)
• D) y(x,t)= +4.0 cm cos(1,200 rad/s)+ (20.0 m^-1 x)
