SUMMARY
The discussion centers on the phenomenon of superimposition in string fundamentals and standing waves. It is established that the fixed ends of a string determine the wavelength, with the fundamental mode representing the longest wavelength where the distance between fixed ends corresponds to two adjacent nodes. The distance between these nodes is precisely half a wavelength. Additionally, the concept of standing waves is explored in relation to electrical signals, where maximum signal transmission occurs at a forward/reflected ratio of 1:1.

The position of the fixed ends of the string determines the wavelength. The fundamental is the longest wavelength of vibration for which the distance between fixed ends is the distance between two adjacent nodes. Any longer wavelength would require the fixed end of the string to move. The distance between two adjacent nodes is 1/2 a wavelength.lektor said:

With a string, what is the standing wave, standing between? 
With electrical signals, standing waves occur within a channel (wire, optical fiber etc.). The signal actually propagates the length of the channel and then radiates back. Maximum signal is transmitted when the forward/reflected ratio is 1:1
Thinking about the standing wave graph (time vs amplitude) that lektor gave, does the acoustic wave propagate out to a boundary and reflect back again to its origin? Where would be the physical position of the origin and boundary?
