To Transmission Line or not to Transmission Line?

Any transmission line CAN be treated, formally, as a transmission line, with all of the associated delays,dispersion etc that implies.  However, if the wavelength of the signal is substantially longer than the length of the transmission line, these effects can be ignored with little loss of precision .. in other words, it CAN be treated as a transmision line but this is not esential. This simple simulation provides a graphic, illustration of the effects that cause this to be so.
