In my textbook they have introduced the concept of longitudinal waves and go on to explain what a compression and what a rarefaction is.It is written-
"In a compression, there is a temporary increase in the density of the medium; and in a rarefaction,there is a temporary decrease in the density of the medium through which a longitudinal wave passes. When the density of the medium increases, its pressure also increases; and when the density of the medium decreases, then its pressure also decreases."
How? Why does the pressure increase if the density increases?Also what is the pressure they are talking about?Is it the pressure the compression exerts on the surround ing medium or the pressure the surrounding medium exerts on the compression ?
