How to Watch Design Squad
Design Squad is available to stream on pbs.org and the free PBS App, available on iPhone, Apple TV, Android TV, Android smartphones, Amazon Fire TV, Amazon Fire Tablet, Roku, Samsung Smart TV, and Vizio.
When you hit the end of a pipe, a sound wave travels down the pipe.
When the wave reaches the end, some of it leaves the pipe and reaches your ear, and part of it reflects back up the pipe.
The air inside the pipe begins to vibrate and produces a tone.
It takes less time for a wave to go up and down a shorter pipe, so the vibration is faster.
And the faster the vibration, the higher the pitch.
That means shorter pipes make higher sounds.
