Multiple Choice
A wave is represented by the equation y(x,t) = 3.2 cm sin(1000 rad/s t - 50 m-1 x) .Another wave is represented by the equation y(x,t) = 4.2 cm sin(1000 rad/s t - 50 m-1 x) .If the two waves interfere destructively,then what is equation that represents the coherent superposition of the two waves?
A) y(x,t) = 7.4 cm sin(1000 rad/s t + 50.0 m-1 x)
B) y(x,t) = 1.0 cm sin(1000 rad/s t - 50.0 m-1 x)
C) y(x,t) = 1.0 cm sin(1000 rad/s t + 50.0 m-1 x)
D) y(x,t) = 7.4 cm sin(1000 rad/s t - 50.0 m-1 x)
