Which parameter is unity in air medium? Explanation: In free space or air medium, the relative permeability is also unity, like relative permittivity. The absolute permeability is given by 4π x 10^-7 units.

Which parameter will be unity for the free space medium?

In free space, which parameter will be unity? Explanation: The relative permittivity is a constant for a particular material. It is unity for free space or air. The absolute permittivity is a constant given by 8.854 x 10^-12 C/m2.

Which of the following parameter gives the phase shift in the electric and magnetic fields in an EM wave?

The phase shift in the electric and magnetic fields in an EM wave is given by which parameter? Explanation: The intrinsic impedance in a conductor is given by η = √(ωμ/2σ) x (1+j). The phase shift is represented by the 1+j term. In polar form it indicates 45 degree phase shift.
