Question

What is the physical significance of wave impedance?

Answer 1

Answer:

wave impedance. where is the magnetic permeability and is the electric permittivity. For free space, these values are 4 × 10-7 H/m (henries per meter) and (1/36 ) F/m (farads per meter), from which 120 , i.e., 377, ohms is obtained. In dielectric materials, the wave impedance is 377/n, where n is the refractive index.
