Plasma frequency Calculator

Property to Calculate:

Plasma frequency (f_p):

Electron density (n_e):

How This Is Calculated

$$ f_p = \frac{1}{2 \pi} \sqrt{\frac{n_e e^2}{\epsilon_0 m_e}} $$ where:

f_p = Plasma frequency (Hz)

n_e = Electron density (electrons/m³)

e = Elementary charge (1.602 x 10^-19 C)

ε₀ = Permittivity of free space (8.854 x 10^-12 F/m)

m_e = Electron mass (9.1094 x 10^-31 kg)

Assumptions

Plasma is uniform and electron density is consistent.
Temperature effects on the electron distribution are neglected.
Collisional effects between electrons and ions are negligible.
The plasma remains incompressible.
