The water at the top of a wave moves blank while the water at the bottom of a wave moves blank

A wave is a periodic or non-periodic change in the physical parameters of a system caused by an action or interaction that propagates at a finite velocity depending on the characteristics of the medium. There are mechanical waves that propagate in material environments and electromagnetic waves that propagate outside any environment. Mechanical waves are further divided into transverse and longitudinal, depending on the trajectory described by the oscillating particles relative to the direction of propagation.

Ifound this on google “here are some features of the alveoli that allow this: they give the lungs a really big surface area. they have moist, thin walls (just one cell thick) they have a lot of tiny blood vessels called capillaries.for more information go to the website below › bitesize › guidesi hope this you for what your looking for. can you plz mark me brainliest?

This is what i found on google“ the monomers combine with each other via covalent bonds to form larger molecules known as polymers. in doing so, monomers release water molecules as byproducts. this type of reaction is known as dehydration synthesis, which means “to put together while losing water. in the process, a water molecule is formed.” i hope this you
