A Wave Is Represented by the Equation Y(x,t) = 3

question 25

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) = 4.2cm sin(1000 rad/s t - 50 m^-1 x) .If the two waves interfere constructively,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)
