Plasma Frequency Calculator: Determine Electron Oscillation

Calculate Plasma Frequency

electrons/m³
Enter the number of free electrons per cubic meter.

Calculation Results

Plasma Angular Frequency (ωp): rad/s

Plasma Frequency (fp): Hz

The Plasma Frequency Calculator helps you quickly determine the characteristic oscillation frequency of electrons in a plasma based on its electron density. Understand collective electron behavior in various materials, from semiconductors to the ionosphere, with this essential physics tool.

Formula:

The plasma angular frequency (ωp) is calculated using the formula:
ωp = √((ne * e²) / (me * ε₀))
Where:

  • ωp = Plasma angular frequency (radians/second)
  • ne = Electron number density (electrons/m³)
  • e = Elementary charge (1.602176634 × 10⁻¹⁹ C)
  • me = Electron mass (9.1093837015 × 10⁻³¹ kg)
  • ε₀ = Permittivity of free space (8.8541878128 × 10⁻¹² F/m)
