Plasma Frequency Calculator

Enter the electron density of a material into the calculator to determine the plasma frequency.

Plasma Frequency Formula

The following equation is used to calculate a plasma frequency.

F = Sqrt [ ( E * C ) / ( P * M) ]

  • Where F is the plasma frequency
  • E is the electron number density
  • C is the electric charge (-1.602176*e^-19)
  • P is the permittivity of a vacuum (8.85418*e^-12)
  • M is the mass of an electron (9.10938*e^-31)

In the above equation, all values are already entered except for the electron number density.

Plasma Frequency Definition

Plasma frequency is defined as the natural frequency at which the plasma of a particular material oscillates.

Plasma Frequency Example

How to calculate plasma frequency?

  1. First, determine the electron number density.

    Calculate the electron number density.

What is plasma frequency?

A plasma frequency is the frequency at which a plasma of a particular material oscillates.

How is plasma frequency calculated?

Plasma frequency depends on 4 values; the electron number density, the electric charge, permittivity, and mass of an electron.
