WebVacuum permittivity, commonly denoted ε0 (pronounced "epsilon nought" or "epsilon zero"), is the value of the absolute dielectric permittivity of classical vacuum. It may also be referred to as the permittivity of free space, the electric constant, or the distributed capacitance of the vacuum. It is an ideal (baseline) physical constant. WebCan we change the upper bound of the speed of light (3*10^8 m/s in free space or vacuum) by propagating it through a dielectric medium of dielectric constant (or refractive …
