The movie at left shows how a standing wave may be created from two travelling waves. If two sinusoidal waves having the same frequency (and wavelength) and the same amplitude are travelling in opposite directions in the same medium then, using superposition, the net displacement of the medium is the sum of the two waves.
Although this equation involves sine and cosine waves, it follows the same conversion equations as do simple vectors. Figure 8-9 shows the analogous vector representation of how the two variables, A and B , can be viewed in a rectangular coordinate system, while M and θ are parameters in polar coordinates.

And we can see that right over here.
Sinusoidal waveforms of the same frequency can have a phase difference. If there is a phase shift (phase difference) or phase delay of the phase angle φ (Greek letter Phi) in degrees it has to be specified between which pure signals (sine waves) this appears. Thus, for example, a phase shift can be between the two stereo
