A wave can only pass through a medium
That means that part of the wave is absorbed by the material.
compressional waves
When a wave passes through the ocean it may make a wave.
When a wave passes through a substance, it gets transmitted through it. The speed of the wave changes depending on the nature of the substance.
That is related to the speed of the electromagnetic wave in the material.
a constructive wave
Seismic Wave. :D
The material through which a wave travels is called the medium.
what happens to interstellear gas as it passes through a spiral density wave
It will be like it was before
Destructive interference takes place. Constructive interference occurs when the trough of one wave passes through the crest of another wave
yes
