how are electromagnetic waves different from mechanical waves?
electromagnetic waves are all high frequency; mechanical waves are all low frequency.
electromagnetic waves can travel through a vacuum; mechanical waves require a medium.
electromagnetic waves are visible; mechanical waves are invisible.
electromagnetic waves always reflect; mechanical waves always refract.

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
