I was wondering if there is a difference between a transverse and longitudinal wave...
Imagine a rubber rod, it flexible to the sides so you can bend it and oscillate it like a string if you do it fast enough. That would be its transverse wave behavior.
Now the same rubber rod can be compressed or decompressed and that would be its longitudinal wave behavior.
Now... what is the difference? in the longitudinal the atoms are contracting and expanding toward each other. And in the transverse movement it is doing the same but at the same time meaning when it bends some part of the radius is been compressed and the outer side is been expanded, but in the end, it is the same.
It could be said that the transverse wave is a complex longitudinal wave.
