If Rowbottom had introduced a flag of half height into the series, as in the black one that I've added to the illustration, is there any way at all, on a flat plane, that the top of that flag could appear in the sightline across the tops of the others?
Asking this elsewhere usually brings out the flattie buzzwords; perspective, diffraction limits, rayleigh criterion, etc.
What say the folks here?
The illustration shows two sightlines; one upward, to the top of the higher flag, and one horizontal, along the tops of the smaller flags. Are we agreed that a sightline to the top of the black flag would be a downward sightline?
