phase constant physics definition
Answers. Best Answer: The phase constant is a measure of how the waveform gets shifted, left or right, along the axis. If you have a basic sine wave, sin(t), you can adjust the amplitude, A sin(t), the frequency, sin(wt), and the phase, or at what point along the curve the signal starts: sin(t + phi). The easiest way to think about phase is to look at t = 0, and see how the waveform starts.
