Resonance: When one object vibrating at the same natural frequency as a second object forces that object into motion.
1. antinodes - areas of complete constructive interference
2. nodes - areas of complete destructive interference
3. harmonics - # of humps Next, we went onto our lab in which we measured the frequencies of our PVC pipes and then figured out which specific notes they corresponded to.
In addition, we also had a little fun with our new instruments by playing songs with them!

RWC:
For those who play the xylophone, they should know that the secret behind playing this fun instrument is that each note produced by hitting the scale is just a different frequency. And that all of the frequencies together produce beautiful music.
