The Physics Philes, lesson 104: Standing O for Standing Waves

The Physics Philes, lesson 104: Standing O for Standing Waves

Now that we have nodes, antinodes, and standing waves under our belt, it’s time to move on to something called normal modes. But wait. Let’s step back a bit. As we were learning about standing waves, we didn’t care so much about the length of the string or what was happening on the free end of the string. But now we need to think about a string of a finite length that is held fix... »

The Physics Philes, lesson 103: Of Nodes and Anitnodes

The Physics Philes, lesson 103: Of Nodes and Anitnodes

Last week we looked at what happens when a wave pulse is reflected off a barrier. But what happens when a sinusoidal wave on a string is reflected? That’s our topic today as we discuss standing waves on a string. In order to do this, we need to use a concept we learned last week called the principle of superposition. To jog your memory, the principle of superposition basically says that we c... »

Awesome Sauce Music Friday! String < Yarn Edition

Awesome Sauce Music Friday! String < Yarn Edition

Hello, darlings! It’s Friday, and, even though it’s summer (maybe especially because it’s summer) it’s time to rock out to science. This week we’re featuring a song by Sarah Donner. I was not familiar with her before her new single blew up in the science-y corners of the Internet this week. It’s called The Rebuttal of Schrödinger’s Cat, but it feels more ... »
