Sound Waves

Compressions and rarefactions are sections of a longitudinal wave. In a compression, the particles are closely packed together, creating a region of high pressure. In a rarefaction, the particles are spread out, leading to a region of low pressure.
The wavelength of a compressional wave is the distance between two adjacent compressions or rarefactions.
A sound wave is made of a series of compressions and rarefactions. Compressions are areas of high pressure where air particles are close together, while rarefactions are areas of low pressure where air particles are spread apart. This alternation of compressions and rarefactions creates the vibration that our ears perceive as sound.
No, compressions and rarefactions are characteristics of longitudinal waves, not transverse waves. In transverse waves, the particles of the medium move perpendicular to the direction of the wave propagation.
Sound waves have compressions and rarefactions. Compressions are areas where molecules are close together, creating high pressure, while rarefactions are areas where molecules are spread out, creating low pressure.
Compressions and rarefactions are regions of high and low pressure in a longitudinal wave, while crests and troughs are points of maximum positive and negative displacement in a transverse wave. Both terms describe different aspects of wave behavior: compressions and rarefactions in longitudinal waves, and crests and troughs in transverse waves.
