Storyboard Text
- FREQUENCY
- AMPLITUDE
- WAVELENGTH
- Frequency is the number of waves to pass a point every second, measured in Hertz (Hz). The frequency of audible sound ranges from 20Hz to 20,000Hz.
- Amplitude is the height of a wave, measured in meters (m). The higher the amplitude the higher the intensity of the wave.
- Wavelength is the length of one wave, measured in meters (m).
- COMPRESSION
- Compressions
- Sound
- RAREFACTION
- Rarefactions
- The part of the wave where the particles are compressed together is called compression.
- The part of the wave where the particles are spread out far apart is called rarefaction.
