What Determines the Physical Size of a Radio Wave's Amplitude?

[fraserev]

hey do you know how to calculate what is the physical size of the amplitude of a radio wave?
like I know how to calculate the wavelength but to draw a scale physical representation of that wave in space, how do I use amplitude to calculate the (y axis) height of the peak periods?

There is no physical relationship between amplitude of a radio wave and size or distance. For illustrative purposes, you just pick a scale that works for your drawing.
