To see how two traveling waves of the same frequency create a standing wave.

Consider a traveling wave described by the formula

y1(x, t)=Asin(kx−ωt).

This function might represent the lateral displacement of a string, a local electric field, the position of the surface of a body of water, or any of a number of other physical manifestations of waves.
