This memory aid covers Memory Aid within Sound Waves for GCSE Physics. Revise Sound Waves in Waves for GCSE Physics with 13 exam-style questions and 15 flashcards. Use this page as part of a wider topic revision path rather than treating it as an isolated fact. It is section 9 of 13 in this topic. Use it for quick recall, then test yourself straight afterwards so the memory aid becomes usable in an answer.
🧠 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.
Practice questions for Sound Waves
What type of wave is sound?
Describe how a sound wave is produced and how energy is transferred by a longitudinal wave.
