rarefactions
In a longitudinal wave moving along a spring, the areas where the coils are the farthest apart are called rarefactions. These are regions of lower density and pressure in the wave where the coils are spread out.
The spring has been stretched. When the coils are squeezed together then the spring has been compressed.
Compression
The region where coils are farthest apart for a compressional wave on a spring coil is the rarefaction zone. In this area, the coils are spread out, producing a lower density of coils compared to the rest of the spring.
In a spring, squeezing some coils together more tightly causes the nearby coils to be more spread apart
In a spring, squeezing some coils together more tightly causes the nearby coils to be more spread apart. So this is how it increases.
In a spring, squeezing some coils together more tightly causes the nearby coils to be more spread apart. So this is how it increases.
When you squeeze together the coils of a spring and then release them, you are creating a mechanical wave known as a longitudinal wave. This wave travels through the spring by causing the coils to compress and then expand in the same direction as the wave's motion.
Compressions my teacher uses the same site for worksheets too email e if u get any more answers in feb im in waves
The places in a wave where the coils are spread apart are called troughs. Troughs are the lowest points of a wave where the amplitude is most negative.
For example, when you have a spring you pull it, and some of it is tight together, and some is spread out. The spread out part is called a Rarefaction and the tight part is compression. The direction it moves is movement of wave, and the opposite side is the movement of coil.
