- The wavelength of a sound wave is the distance between two consecutive crests or troughs.
- It is measured in meters (m) and denoted by the symbol λ (lambda).
- The wavelength is inversely proportional to the frequency of the wave.
2. Frequency:
- The frequency of a sound wave is the number of oscillations or vibrations that occur in one second.
- It is measured in Hertz (Hz), which is equivalent to one oscillation per second.
- The frequency determines the pitch of a sound, with higher frequencies producing higher-pitched sounds.
3. Time Period:
- The time period of a sound wave is the time taken for one complete oscillation or vibration.
- It is measured in seconds (s) and is denoted by the symbol T.
- The time period is inversely proportional to the frequency of the wave.
4. Amplitude:
- The amplitude of a sound wave is the maximum displacement of the particles from their equilibrium position.
- It is measured in meters (m) or Pascals (Pa) and is denoted by the symbol A.
- The amplitude determines the loudness of a sound, with higher amplitudes producing louder sounds.
