Let us arrange a coherent monochromatic light beam, e.g. a laser beam, to
be split and directed along two paths. With repect to the light's
wavelength, the paths are suitably arranged such that a half-cycle net
time delay exists between them. These beams are then recombined
downstream, so as to destructively interfere there. Question: where
does the light energy "go"?
