Interference

This reminds me of a high school physics project. I was in a group with classmate Bob McMasters, who had, what I thought at the time was, a fancy camera. He took photographs of the ripples in a pan of water so we could analyze the interference patterns. Hence the title for today’s post.

There are two dominant sources of the interference patterns from a rowing shell:
» the bow of the shell pushing water away (the inverted-V pattern)
» the stern of the shell moving through the water (leaving a V-shape as the water fills the space the shell has vacated).

Similar post many years ago. I think I was going faster today: compare them side-by-side.
» Not to be confused with “puddles,” which are also apparent above, though not as pronounced as in the earlier post.

Nice symmetry.
