It's called the rarefaction (as opposed to the compression)
This type of wave is a compressional wave, also known as a longitudinal wave. In this wave, the particles move parallel to the direction of the wave propagation, causing regions of compression and rarefaction as it moves through a medium. Examples of compressional waves include sound waves.
The regions in a sound wave where particles are farther apart are called rarefactions. This is where the pressure is lower compared to the surrounding areas.
compression
A vibration that spreads away from a vibrating object is called a wave. Waves are disturbances that transport energy from one place to another through a medium such as air, water, or solids.
As a sound wave travels away from the source, its energy spreads out over a larger area, leading to a decrease in the intensity of the sound. This reduction in energy leads to a decrease in the loudness of the sound as it travels farther away.
The sound wave will travel faster in the medium where particles of matter are further apart because there will be less resistance and the particles are more spread out, allowing the wave to propagate more easily.
rarefaction having low pressure............
The rarefaction is the area of a sound wave where particles are less dense. This corresponds to the regions of lower pressure within the wave, where particles are spread out farther apart from each other.
The amplitude of a circular water wave generally decreases as it spreads out. This is due to energy being transferred from the wave to its surroundings, causing a gradual damping of the wave amplitude.
No, a sound wave is a compressional wave.
The less dense areas in a sound wave are called rarefactions. These are regions where the air particles are spread farther apart, causing a decrease in air pressure.
Type your answer here... this is called a compression, and when they are spread apart it is called a rarefaction
