Waves

This is going to consist of me refreshing my high school math knowledge.

• The crest of the wave is the peak
• The trough of the wave is the bottom
• The height of the wave is the distance between the crest and the trough
• Amplitude ($A$) is half of the height of the wave.
  • In sound waves, this value represents the loudness
• Period ($T$) is the time it takes for a wave to travel through a single wavelength
• Frequency ($f$), measured in Hertz (Hz) is the number of times a wave passes through a fixed point in a second
  • $f = \frac{1}{T}$
  • This gives the pitch
• Wavelength ($λ$) is the distance from one crest to the subsequent crest (or trough to trough)¹
