I read in my student's book that elastic waves can be transverse and longitudinal. After a little research I knew that there is an elastic solid (not an elastic wave).
I can imagine a longitudinal wave (the horizontal spring example), but was interested in the case of transverse elastic wave.
Here, "Transverse waves commonly occur in elastic solids", I want to see the effect of elasticity in a transverse wave. The easiest example to me of a transverse wave is the experiment of a rope, fixed in one end, and in the other end moved up and down fast vertically (back to the original horizontal level). But this is not applicable for the concept of elasticity, since each set of particles of the rope are due to constantly (continuously) driving force which finally sets the particles back to their original calm horizontal level with a null force (as far as I can imagine), so the question of elasticity doesn't hold here since it deals with the case of what comes after a non-null force with deformation of the object.
Can someone give an example? Is the book's sentence correct ?
