- Homework Statement:
- Determine the value of optical impedance

- Relevant Equations:
- Z = μ . c/n

Hi,

It's given that an electromagnetic wave (5.10^14 Hz) travelling in an environment with the index n = 1,33, where the magnetic permeability (μ) is equal to the magnetic permeability in a vacuum (μ0).

The optical impedance (Z) is given by the formula : Z = μ . c/n.

I tried to turn μ into μ0 to determine its value but I didn't manage to get any further than determining the value of the relative electrical permittivity (εr) = 1,769.

Sorry if I have misused any vocabulary because I'm translating this from french.

Thank you so much for your help!
