🧠 Memory Aid
Sound speed order: "Sounds Go Louder Solidly" — Gas (slowest), Liquid, Solid (fastest). Or remember: denser and more rigid = faster.
Oscilloscope trace — what changes what:
- Amplitude = how tAll the wave is = how Loud (A and L both go together)
- Frequency = how Frequently packed the waves are = Pitch (F and P both go together)
Echo distance formula: "Half the time, all the distance" — divide the total time by 2, THEN multiply by speed.
