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)
