Here is the question….
Is the shadow a zig zag or is it the shadow a straight line that falls on a zig zag? Questions to ponder.
I’ll guess the second one – shadow is a straight line that falls on an uneven surface. Do I win anything?
I think I am in agreement with you guys. You win my undying devotion… which really isn’t worth much after the recession hit: devotion stocks sure took a tumble.
Clearly the shadow is a diffusion pattern from the incident rays of what we can take to be a planar field with a known line of action striking a surface consisting of one or more planes not parallel (though not necessarily perpendicular) to the direction of wave propagation. Duhhhh.
