🔬 The Physics of Sound

  • Frequency (Hz): Determines the pitch. Low numbers (e.g., 60 Hz) produce deep bass. High numbers (e.g., 1000 Hz) produce high-pitched beeps.
  • Amplitude: How "tall" the wave is, which translates to volume or loudness.
  • Sine Wave: A pure, smooth tone with no harmonics.
  • Square/Sawtooth: Contain many "harmonics," giving them a buzzy or raspy sound reminiscent of old 8-bit video games!

WARNING: Keep volume low when testing high frequencies, especially with headphones.
