If the
wave function isn't actually real, what creates those light and
dark bands?
Short - wavelength light bounces back and forth between the ends of the guide, and the peaks and troughs of the counter-propagating light
waves overlap to create a pattern of bright and
dark bands much like the pressure patterns with a ringing organ pipe.
In optics the double - slit experiment showed the interference of two slightly displaced light
waves of the same frequency gives rise to a series of alternating
dark and bright
bands.
As the
waves spread out beyond the slits they interfere, giving a distinctive pattern of pale and
dark bands when the light strikes a background screen.
