Rarefaction is the part of the sound wave where the air particles are the farthest apart from each other. It's like the "trough" of a transverse wave. The size of this part affects the wavelength and amplitude of the sound produced, which changes the volume and pitch. Note that there's also another part of the wave called "compression". This is like the "peak" of a transverse wave.

How are rarefraction and reflection manifiested in sound?
Rarefaction in sound refers to the decrease in air pressure caused by a sound wave, leading to the expansion of air molecules. Reflection in sound occurs when a sound wave strikes a surface and bounces back, creating an echo or reverberation effect.
What is determined by the amount of energy a sound wave carries?
The intensity of a sound, which determines its loudness, is determined by the amount of energy a sound wave carries. This energy is influenced by the amplitude of the wave, with higher amplitudes corresponding to louder sounds.
What does a rarefraction mean?
A rarefaction is a decrease in density or pressure in a medium, typically related to the spreading out of waves. In the context of sound waves, rarefaction is the region in a longitudinal wave where the particles are farther apart.
What are areas of compression and rarefraction?
In a sound wave, compression areas are where the air particles are closely packed together, resulting in high pressure. Rarefaction areas are where the air particles are spread out, resulting in low pressure. These alternating areas of compression and rarefaction create the vibrations that we perceive as sound.
What does a combination of a compression and a rarefraction create?
A compression and a rarefaction together create a sound wave in a medium. This alternating pattern of high-pressure zones (compressions) and low-pressure zones (rarefactions) propagates through the medium, carrying the energy of the sound wave.
