standing waves
Mar. 2nd, 2004 02:02 amThe fellow who does such things came by today to replace my garbage disposal, whose out-of-whackness made pretty ripples yesterday. I hadn't taken pictures yet! But he had forgotten his plumber's putty. While he went and got that, I took some stills and some movies, which turn out to catch it far better. He said that a friend who does concert light shows should use these patterns.
Movies will stay up for a few days:
waves forming, rapidly, in a plate (.MOV, 3.7 megs).
and more reluctantly in a bowl, but the bowl has its own ideas (8.9 megs).
Stills:
The new garbage disposal is named Badger 1. It does not vibrate. Anyway maybe I need a rig with controllable frequency; maybe also amplitude; ideally, trajectory is an ellipse, eccentricity modulable from circle to line, of any spatial orientation I desire.
