That sounds more like ohms law .
Its a bit more complicated than that im afraid , I have dealt with this type of reflection before with fast rise signals and long wires , it causes noise and distortion and reflected power back to the chip output , it happens when you have long transmission lines and impedance mismatch , the problem is always worst when you are dealing with capacitive loads.
I view the wfc as an antenna , reflection is not something we want , this is not a radar sysem
Remember that Stan knew much about antennas and radar .
