SUMMARY

The physical size of a radio wave's amplitude does not have a direct relationship with its size or distance. To represent the amplitude visually, one must select an appropriate scale for the drawing rather than relying on a mathematical calculation. The amplitude can be depicted on the y-axis of a graph, but the actual height of the peaks is determined by the chosen scale rather than any inherent property of the wave itself.

PREREQUISITES
  • Understanding of radio wave properties
  • Familiarity with wave terminology (wavelength, amplitude)
  • Basic graphing skills
  • Knowledge of scale representation in illustrations
NEXT STEPS
  • Research methods for visualizing waveforms in physics
  • Learn about the relationship between amplitude and energy in electromagnetic waves
  • Explore tools for graphing wave functions, such as MATLAB or Python's Matplotlib
  • Investigate the principles of wave representation in engineering applications
USEFUL FOR

Students in physics, educators teaching wave properties, graphic designers illustrating waveforms, and engineers working with electromagnetic theory.

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.
