What is difference between absolute permittivity and relative permittivity of medium?
The absolute permittivity of a medium is its relative permittivity multiplied by the vacuum permittivity. The absolute permittivity is a proportionality constant between the electric and displacement field with units of Farad/meters (in SI units). This number is usually very small (e.g. for air: 0.000 000 000 008 85 F/m). The relative permittivity is a unit-less number scaled upward to present nicer numbers (e.g. for air: 1.0005). To get the absolute permittivity from the relative permittivity one should multiply with the vacuum permittivity: 8.85418781... E-12 F/m.
What is dimension of permittivity of vacumm?
The dimension of permittivity of any medium or vacuum (free space) is C2 N-1 m-2
What is permittivity of diamond?
According to Wikipedia, below, the relative permittivity of diamond is 5.5-10, given that:"The relative permittivity of a material under given conditions reflects the extent to which it concentrates electrostatic lines of flux. In technical terms, it is the ratio of the amount of electrical energy stored in a material by an applied voltage, relative to that stored in a vacuum. Likewise, it is also the ratio of the capacitance of a capacitor using that material as a dielectric, compared to a similar capacitor that has a vacuum as its dielectric."
What is the value of epsilon in physics?
epsilon generally tends towards zero. if you mean the relative permittivity epsilonr it is material dependent
What is the effect of mediam in coulombs law?
It is experimentally observed that if an insulator is used as medium in place of air or vacuum, the force between the electric charges is reduced by a factor "Er".

What is meant about di-electric constant?
The relative permittivity of a material is its dielectric permittivity expressed as a ratio relative to the permittivity of vacuum.Permittivity is a material property that expresses the force between two point charges in the material. Relative permittivity is the factor by which the electric field between the charges is decreased or increased relative to vacuum.Likewise, relative permittivity is the ratio of the capacitance of a capacitor using that material as a dielectric, compared to a similar capacitor that has vacuum as its dielectric. Relative permittivity is also commonly known as dielectric constant, a term deprecated in physics and engineering.
What is relative permittivity if dielectric constant of water is 80.10?
'Dielectric constant' is an archaic term for relative permittivity. They are one and the same.
What is the relative permittivity of indium arsenide?
14.6
What is the relative permittivity of wood?

What is Relative dielectric constant for vacuum?
YES IT IS. Any quantity which is ratio of two physical quantities having same unit is dimensionless. Dielectric constant is ratio of Permittivty of medium to the permittivity of free space. As Permittivity of medium and permittivity of free space both have same units(F/m ie Farad/meter) dielectric constant becomes dimensionless quantity

The speed of light depends on?
... the electrostatic permittivity and the magnetic permeability of the medium. As a matter of fact, the speed of light in the medium is the reciprocal of the square root of their product.
What is magnetic permeability of materials?
Relative permittivity or dielectric constant of a medium is defined as the ratio of force between two charges separated by a certain distance in air or vacuum to the force between the same charges separated by the same distance in the medium.According to American Heritage Dictionary:permittivitySYLLABICATION: per·mit·tiv·i·tyPRONUNCIATION: PERM eh TIV eh TEENOUN: Inflected forms: pl. per·mit·tiv·i·tiesA measure of the ability of a material to resist the formation of an electric field within it. Also called dielectric constant, relative permittivity.
What is the value of epsilon in physics?

When electromagnetic waves are moving through matter the speed of electromagnetic waves depends on?
Velocity of light in a medium depends on the electric and magnetic properties of that medium, namely permittivity, and permeability.
