Compression is the region of a longitudinal wave in which the density and pressure are at a maximum. Rarefaction is the region of a longitudinal wave in which the density and pressure are at a minimum.
Mechanical waves are waves that need a medium to go through. Some examples are ocean waves, seismic waves, and sound waves. Also when a slinky moves back and forth or at right angles it is like a wave.
The optical density of a medium is not the same as its physical density. The physical density of a material refers to the mass/volume ratio. Optical density determines how much a light wave is slowed down as it passes through a medium. The more optically dense a material is, the slower that a wave will move through the material.The refractive index is a measurement of optical density. A medium with a low optical density, would have also a low refractive index.For example air, having a low optical density has a refractive index of 1.0003, whereas water, with a higher optical density, has a higher refractive index of 1.333.
A mechanical wave is not an electromagnetic wave.
When a hockey ball is struck by a player, the impact is short and localized, which does not generate enough force to create a wave-like motion. In contrast, when a ball is dropped into water or a string is shaken, there is a consistent and continuous force applied over a larger area, allowing waves to form. Additionally, the density and compressibility of the medium also play a role in wave formation.
True. Electrons in atoms can exhibit wave-like behavior as described by quantum mechanics. This means they can be described by a wave function that gives information about their probability distribution in space and can exhibit interference patterns similar to waves. This duality between particle and wave behavior is a fundamental aspect of quantum mechanics.
The part of a compressional wave with the greatest density is the compression region, where particles are closest together due to the wave's compressional nature. This region represents the highest density of particles in the wave's pattern.
In a compressional wave, the particles are spaced farthest apart at the points of maximum rarefaction where the wave is at its trough. This is when the pressure is at its lowest and the particles are more spread out.
The part of a longitudinal wave with the lowest density is the rarefaction. This is where the particles are spread out, creating a region of lower density compared to the rest of the wave.
The particles in a compressional wave are spaced farthest apart at the rarefaction region, which corresponds to the trough of the wave where the pressure and density are lower than normal.
low density.
The part of a longitudinal wave with the lowest density is the rarefaction, where the particles are spread apart and the pressure is lower than the surrounding medium.
The area of greatest density in a compressional wave is the region where the particles are compressed together, resulting in a higher density of particles compared to areas of lower density. This occurs in the compressed regions, or peaks, of the wave where particles are closest together.
In a compressional wave, the density of the medium varies periodically as the wave travels through it. This variation corresponds to the peaks and troughs in a transverse wave, where the denser regions represent the peaks of compression and the less dense regions represent the troughs of rarefaction. However, in a compressional wave, this density variation occurs in the same direction as the wave propagation, whereas in a transverse wave it occurs perpendicular to the direction of wave propagation.

A rarefaction is found in a compressional wave
The rarefaction is the part of a compressional wave where particles are far apart. This is the region of low pressure in the wave, where particles are spread out compared to the other parts of the wave.
