WebApr 8, 2024 · The permittivity of a material is represented by the symbol ε. The SI unit of permittivity is Farad per metre. The approximate value for permittivity is 8.85 X 10-12 Faraday/metre, which is found in a vacuum medium. The permittivity measures the number of charges needed for generating a unit of electric flux in a specific channel. WebSubstituting equation 4 into the above equation leaves us with: We can conclude that the speed of the electromagnetic wave in vacuum is the reciprocal of the square root of permeability of vacuum multiplied by the permittivity of vacuum.
