## Background

The electron is an incredibly difficult particle to find, let alone measure. However, the electron classical radius is used throughout physics equations as a value that has been derived, rather than a direct measurement of the particle. The radius is the distance from the electron’s core to the edge of the particle.

## Energy Wave Constants – Equivalent

The following is the representation of this fundamental physical constant expressed in energy wave theory. Using energy wave constants, its value was calculated and shown to match the known value in the Summary of Calculations table.

### Electron Classical Radius

Particles have a defined radius as eventually its standing waves, which defines its mass and potential energy, converts to traveling waves at this edge (radius). Traveling waves still have an effect on other particles although amplitude decreases with the square of the distance from the core (the traveling waves are calculated accurately to be the electric force). The electron has 10 wave centers (K=10), and these wave centers have an effect on the particle’s wavelength and amplitude. Amplitude is constructive, and becomes K * A_{l} (amplitude); likewise wavelength becomes K * λ_{l} (wavelength). There are a total of K standing waves in each particle, so for the electron, this is 10 wavelengths, or K wavelengths. Thus the radius becomes the number of wavelengths K, multiplied by the electron wavelength distance in meters, K * λ_{l}. This is K^{2 }λ_{l}.

This is the complete derivation of this equation, but further explanation, including a visual of the electron, is available in the Fundamental Physical Constants paper.
