Hi,
I'm looking through my notes on em waves in dielectrics and the fresnel equations and I've been stuck on this for a while.
It states that if the complex amplitude = E0eiΦ is positive there is no phase change. However when the value is negative, the phase change Φ is π.. Why is that?
Thanks in advance!
