Hi there,
I have noticed that when the wadding pool I work at is draining, a small whirlpool appears over the drain in the center of the pool. When the sun is shining a shadow appears at the bottom of the pool(2.5-3 feet deep) below the whirlpool. The shadow is larger than the whirlpool itself, or at least larger than the amount of water that is noticeably moving.
Using my knowledge of physics, I hypothesized the moving water perhaps diffracts the incoming photons so that a minimal amount pass through, therefore causing the shadow at the base of the pool? Any help would be greatly appreciated, this has been really bugging me.
Please excuse my grade 12 knowledge of physics.
P.S. I took a picture, but cannot upload it due to iphoto "unexpectedly quitting" on me whenever i try to open it, i hope i have been descriptive enough.
Thanks,
Eric
