What does amplitude mean?

Explanation:
Amplitude is the height of a radio wave—the maximum strength of its electric and magnetic fields. This height reflects how strong the signal is and how much power reaches an antenna (with intensity roughly proportional to the square of the amplitude). It is not about how fast the wave moves (speed), how often it cycles (frequency), or the orientation of the field (polarization). Think of amplitude as the signal’s strength: higher amplitude means a stronger, more easily received signal.
