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