Physics behind signal reflections and series termination

Do USB Data Wires (D+/D-) have 90 ohm differential impedance and single ended 45 ohm impedance to ground and if so how is this made?

Impedance of an Edge-Coupled Coplanar Waveguide With Ground

Consensus on microstrip trace impedance calculations?

A transmission line with continuously varying impedance, how would reflection occur in this case?

How can PCB trace have 50 ohm impedance regardless of length and signal frequency?

Why Characteristic Impedance must be 50 ohms?

Transmission line reflection. I would like a non-mathematical explanation
