The DOUBLE SLIT phenomenon is FULLY EXPLAINED with Pure Classical Reasoning.

 Thus, the DOUBLE SLIT experimental results for BOTH Waves and Charged Particles is

...NO PARADOX...

SCROLL DOWN

and

TAKE A LOOK

CYLINDRICAL  WAVES  are re-emitted in each case by SHARP EDGE re-emitters

A DOUBLE SLIT (four edges) re-emits FOUR CYLINDRICAL WAVE FRONTS to INTERFERENCE SCREEN

(one slit, either A or B, is blocked at a time, thus altering the interference pattern)

SINGLE SLIT (two edges) EMIT CYLINDRICAL WAVE FRONTS from ELECTRON EXCITATION

(lower edge is blocked by DETECTOR altering the interference pattern of single slit)

DOUBLE SLIT (four edges) EMIT CYLINDRICAL WAVE FRONTS from ELECTRON EXCITATION

(lower slit containing two edges is blocked by DETECTOR, thus altering the interference pattern of the double slit)
