Three Traveling Sinusoidal Waves Are on Identical Strings, with the Same

question 9

Multiple Choice

Three traveling sinusoidal waves are on identical strings, with the same tension.The mathematical forms of the waves are y₁(x,t) = y_msin(3x - 6t) , y₂(x,t) = y_msin(4x - 8t) , and y₃(x,t) = y_msin(6x - 12t) , where x is in meters and t is in seconds.Match each mathematical form to the appropriate graph below.

• A)y₁: i, y₂: ii, y₃: iii
• B)y₁: iii, y₂: ii, y₃: i
• C)y₁:i, y₂: iii, y₃: ii
• D)y₁: ii, y₂: i, y₃: iii
• E)y₁: iii, y₂: i, y₃: ii
