      Phase shift is any change that occurs in the phase of one quantity, or in the phase difference between two or more quantities.[1]
      \phi\, is sometimes referred to as a phase shift or phase offset, because it represents a "shift" from zero phase. But a change in \phi\, is also referred to as a phase shift.
      For infinitely long sinusoids, a change in \phi\, is the same as a shift in time, such as a time delay. If x(t)\, is delayed (time-shifted) by \begin{matrix} \frac{1}{6} \end{matrix}\, of its cycle, it becomes:
      x(t - \begin{matrix} \frac{1}{6} \end{matrix}T) \, = A\cdot \cos(2 \pi f (t - \begin{matrix} \frac{1}{6} \end{matrix}T) + \phi) \,

      = A\cdot \cos(2 \pi f t - \begin{matrix}\frac{\pi }{3} \end{matrix} + \phi ),\,
      whose "phase" is now \phi - \begin{matrix}\frac{\pi }{3} \end{matrix}.   It has been shifted by \begin{matrix}\frac{\pi }{3} \end{matrix} radians.

      Phase difference is the lead or lag, expressed in degrees or radians, between two waves having the same frequency and referenced to the same point in time. The diagram on the left shows the y versus t graph and the diagram on the right shows y versus x, both graphs represents the blue wave leading by the red wave by 60 degree or \begin{matrix}\frac{\pi }{3} \end{matrix} radians.
