The hypnotic power of pendulum waves
Lesson created by Chris Anderson using
Video from Harvard Natural Sciences Lecture Demonstrations YouTube Channel
Here's a remarkable video on YouTube from Harvard's NatSciDemo channel. Fifteen uncoupled simple pendulums of monotonically increasing lengths dance together to produce visual traveling waves, standing waves, beating, and (seemingly) random motion. In 2 mins, you can get an insight on why waves are so intriguing. This video is relevant to music, to string theory, and much more.
