Hi there! In this issue we will talk about the sound and its propagation in the air. Let's analyze all the sound propagation features: Every sound, once generated by a vibrating elastic body, is transmitted through the surrounding medium, creating a series of waves where particles the medium is composed of are subject to condensation and rarefaction. It could seem pretty obvious, but it's better to point out that a mean of conduction is essential for sound transmission. No transmission is possible in vacuum, differently to what happens for light transmission. Here we are with some frequency values and relevant…
