WebMar 16, 2024 · It's c = 1/√(ε 0 μ 0) where ε 0 is vacuum permittivity and μ 0 is vacuum permeability. There’s a reciprocal because permittivity is a “how easy” measure rather than a “how hard” measure. Permittivity is effectively the inverse shear modulus for an electromagnetic wave in space, whilst permeability is effectively the density.

WebJan 22, 2005 · just pick any two numbers that do this. epsilon x mu = 1/299792458 2. and anything will be fine, it just affect comparative sizes of magnetic and electric units. you can even make one of them something crazy like 4 times pi time. one over tenmillion, and it's cool, those two numbers can be epsilon-naught and mu-naught. Vacuum 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) … See more The value of ε0 is defined by the formula $${\displaystyle \varepsilon _{0}={\frac {1}{\mu _{0}c^{2}}}}$$ where c is the defined value for the speed of light in classical vacuum in SI units, and μ0 is the parameter … See more By convention, the electric constant ε0 appears in the relationship that defines the electric displacement field D in terms of the electric field E and classical electrical polarization density P of the medium. In general, this relationship has the form: See more 1. ^ "2024 CODATA Value: vacuum electric permittivity". The NIST Reference on Constants, Units, and Uncertainty. NIST. 20 May 2024.
