The Physics Philes, lesson 112: Sea Shell Resonance

I know last week I said that we’d look at how standing sound waves applied to musical instruments, but as I was preparing I realized that it doesn’t really illuminate anything, so I’m moving on resonance and sound. Sound good to you? Great. Remember that a normal mode is when …

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 …
