If I have a finite boundary, say of length L. Is it possible to demonstrate that if I were to allow all possible CONTINUOUS values of a wave to exist (with unit amplitude) then deconstrutive interference destroys all waves except those with wavelength:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]k=\frac{n\pi}{L}[/tex]

Where n =0,1....

Thanks!
