rarefactions
The spring has been stretched. When the coils are squeezed together then the spring has been compressed.
Compression
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.

Compressions my teacher uses the same site for worksheets too email e if u get any more answers in feb im in waves
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.
It is compressions

Surface wave
longitudinal. this is like a sound/pressure wave or how automotive traffic flows. the other type of wave is a transverse wave which describes propagation of EM radiation.
