What is the term for the less dense part of a longitudinal wave?

The less dense part of a longitudinal wave is called the rarefaction. It is the region where the particles are spread out and have lower pressure compared to the denser region called compression in a longitudinal wave.


What is the less dense part of a compression wave called?

Rarefaction is the less dense part of a compression wave where the particles are spread apart.


What less dense region of a longitudinal wave?

The less dense region of a longitudinal wave is called a rarefaction. In this region, the particles are spread apart, leading to a decrease in density compared to the surrounding areas.


How does compression affect the propagation of a longitudinal wave?

Compression affects the propagation of a longitudinal wave by increasing the density of the medium, which in turn increases the speed of the wave. This results in the wave traveling faster through the compressed region compared to a less dense region.


How dense a medium is in a compression part of the wave and how empty the rarefied area is?

In the compression part of a wave, the medium is more dense as the particles are packed closely together. In the rarefied area, the medium is less dense and the particles are further apart.


What is the region of a longitudinal wave in which the density and pressure are less than normal?

The region of a longitudinal wave where the density and pressure are less than normal is called rarefaction. In this region, particles are more spread out and the pressure is lower than in surrounding areas.


What makes less dense air come from the equator?

Air becomes more or less dense relative to its temperature. Cold air is denser than warm. Since the equatorial region is tropical, the air will be warmer and less dense.


What is the term for the dense part of a longitudinal wave?

According to my textbook it says rarefaction, is the less dense region of a longitudinal wave


The tendency of a less dense substance to float in a more dense liquid is called what?

The tendency of a less dense substance to float in a more dense liquid is called buoyancy. Acids are substances that form hydronium ions when dissolved in water.


How is the Earth layers formed?

Earth is layered due to gravitational compression that caused dense materials to sink onto the Earth's center, while the less dense materials rose.


What is it called when something is not as dense as water?

When something is not as dense as water, it is said to be less dense or have a lower density than water.


What is the lighter-colered region around the dark center of a sunspot called?

The lighter-colored region around the dark center of a sunspot is called the penumbra. It consists of less dense magnetic field lines compared to the umbra, which is the darkest part of the sunspot.
