If you connected a DC or AC source to the end of an single, infinitely long, straight wire suspended in free space (separated from anything), would propagation occur along the line?

Signal propagation is the process by which a signal travels through a medium, such as air or a wire. It occurs through the transfer of energy from one particle to another, creating a wave-like motion that carries the signal.
The speed and strength of signal propagation are influenced by various factors, including the type of medium, distance, interference, and the frequency and power of the signal being transmitted.
As a signal propagates through a medium, its strength decreases due to factors such as attenuation, absorption, and scattering. This means that the signal becomes weaker the further it travels, and may require amplification to maintain its strength.
The signal to noise ratio is a measure of the strength of a signal compared to the level of background noise. As a signal propagates, it may encounter interference and other sources of noise, which can decrease the signal to noise ratio and affect the quality of the signal.
Wireless communication relies on signal propagation to transmit information through the air. The strength and quality of the signal can be affected by factors such as distance, obstructions, and interference, which can impact the reliability of wireless communication.
