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 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 the dimensional formula for permittivity of free space?
Permittivity =[Ɛo] = [Charge]2 /([Force] [Distance]2) =[TA]2 / [MLT-2] [L]2{[A] is the dimensional formula of electric charge} =[TA]2 / [ML3T-2] =[M-1L-3T(2+2)A2] = [M-1L-3T4A2]
What is the physical significance of permeability and permittivity. how they relate to each other.?
It is basically the scale factor between the unit of force and the unit of charge. There are actual electric and magnetic unit systems in which there is no such factor (since it would be 1). For most of our experiences we insist on measuring charge in coulombs and measuring forces (or electric fields) in Newtons (Newtons per coulomb). The coefficient that we need to make it come out right is related to the permittivity of free space. The words probably go back to the days when we thought there was an ether in space. You can also think about it as the way space effects the forces between two charges. In this way it become s a property of space.
What is the difference between complex permittivity and static dielectric conatant?

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

How do you calculate speed of light in a vacuum?
-- look up the electrostatic permittivity of free space -- look up the magnetic permeability of free space -- multiply them -- take the square root of the product -- take the reciprocal of the square root The number you have is the speed of light in a vacuum.
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 the dimensional formula of permittivity of free space?
Permittivity =[Ɛo] = [Charge]2 /([Force] [Distance]2) =[TA]2 / [MLT-2] [L]2{[A] is the dimensional formula of electric charge} =[TA]2 / [ML3T-2] =[M-1L-3T(2+2)A2] = [M-1L-3T4A2]
Why electromagnetic rays do not require any medium?
Because electromagnetic wave propagation is nothing but the propagation of electric and magnetic energy. Free space has the characteristics such electrical permittivity and magnetic permeability. So in modern terms free space is also considered as a medium but of course a non material medium.
