When a plane wave for example is travelling from air-->dielectric and we know the power flow of the incident and transmitted wave (i.e 200mW/m^2 and 150mW/m^2) with no info about the dielectric constants of the 2 materials or the impedances.
Is there a way that I can conclude between the difference in propagation speeds in these 2 media?
