Enter the electron density of the 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

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