Abstract

I have done demonstrations of audible beats with tone bars, with function generators and speakers, and with resonating columns, and also visible beats with combs.1 In looking for a new beats demonstration, I regretted never having taken a picture of an overpass with wire fencing on both sides: the otherwise identical fencing shows visual beats because the two repeating patterns are at different distances from the observer.
