Hi,
For a wave fixed at both ends, what is the behaviour of the original and refelcted wave between the harmonic frequencies?
I understand how a standing wave is created by the superposition of a wave and it;s reflection at a boundary. I also understand that at the fundamental frequency of the standing wave will be half a wavelength ( a node at each end and an antinode in the middle) and a full wavelength at double that frequency (with 3 nodes and 2 antinodes).
But what I can't figure out is what would the original and reflected waves look like between the resonant frequencies?
I know that at the ends they must cancel, so how does this effect the reflected wave?
Also is the reflected wave reflected again each time it meets a boundary?
Any help would be greatly appreciated?
An animation here clearly shows how the waves cancel at each end. But what about when the frequency is not right for a standing wave with nodes not at the ends exactly?
Any help would be greatly appreciated.
thanks,
Shane
