How is amplitude represented on the sine wave?

Amplitude is the height of the sine wave—the maximum displacement from the center line. In practical terms, for a sine wave centered at zero, it’s the distance from the horizontal axis to the peak, which in electrical signals is the peak voltage. This value stays the same regardless of how fast the wave repeats, which is set by frequency. The angle of rotation describes phase, not height; the width of the waveform isn’t about amplitude; the period of repetition concerns how long one cycle lasts. Remember, the peak-to-peak value is twice the amplitude since it spans from −A to +A.
