Compression refers to the region of a longitudinal wave where the particles are closest to each other, while rarefaction refers to the region of a longitudinal wave where the particles are farthest apart from each other. This basic foundation of a longitudinal wave, including compression and rarefaction, differs from other waves containing crests and troughs.Know More
Sound waves can be classified as mechanical, pressure or longitudinal waves. When sound waves are transferred through a medium, which can be any material via particle-to-particle interaction, the wave is classified as mechanical. Sound waves can also consist of high- and low-pressure patterns transferring through a medium; in these instances, the sound wave is classified as a pressure wave. However, these two classifications are typically marked by crests and troughs throughout the wave, rather than compression and rarefaction.
Longitudinal waves often result from sound moving through air specifically. Particles in the air are affected in a direction that is parallel with the direction in which the sound energy is moving. This difference in the particles' reactions when a sound energy wave moves through the air results in compression and rarefaction, rather than crests and troughs.
The source of the sound is irrelevant to the type of wave produced. Instead, the type of sound wave depends more heavily on the medium through which the sound wave travels. If the sound wave travels through the air, it will result in a longitudinal sound wave, marked by compression and rarefaction.Learn more about Optics & Waves
Sound is a mechanical wave resulting from the back and forth vibration of the particles of the medium through which the wave is moving. The compressions and rarefactions of sound waves move parallel to the direction of wave propagation, making sound a longitudinal wave.Full Answer >
When charged particles and x-rays emitted from solar showers impact Earth's atmosphere, they can disrupt both high- and low-frequency radio transmissions, and in some extreme cases, can cause total radio blackouts for hours at a time, explains NASA. Extreme radio blackouts can last for hours, may cause GPS to be off by as much as a mile and even affect the positioning systems of satellites in low Earth orbit.Full Answer >
Sound waves transfer energy by causing successive compressions and rarefactions in the particles of the medium without transporting the medium particles themselves. Sound in solids can also manifest as transverse waves, causing crests and troughs in the propagation medium.Full Answer >
According to the Old Dominion University, sunsets get their red color because light is refracted by particles that are in the atmosphere and the red spectrum is the one that is visible. The sky can also have shades of orange, yellow and purple when the sun begins to set.Full Answer >
