WebMar 30, 2024 · Example When a vibrating object moves forward in air as medium, it pushes and compresses the air in front of it creating a region of high pressure. This region is called a compression. What is general … WebCheck Your Understanding. 1. A sound wave is a pressure wave; regions of high (compressions) and low pressure (rarefactions) are established as the result of the vibrations of the sound source. These compressions and rarefactions result because sound. a. is more dense than air and thus has more inertia, causing the bunching up of sound. WebThe sample can be a vector giving the sample sizes for each row. If the sample size is equal to or larger than the observed number of individuals, the non-rarefied community will be returned. The random rarefaction is made without replacement so that the variance of rarefied communities is rather related to rarefaction proportion than to the ... strong outdoor lights
