1. The problem statement, all variables and given/known data Please explain the difference and try to give examples. I know that the displacement of the medium in a transverse wave is perpendicular to the direction of wave travel and in longitudinal is parallel to the direction of wave travel, but does this mean that transverse waves only travel from left to right? 2. Relevant equations Conceptual question 3. The attempt at a solution I've stated what I know above, and what I'm confused about. Please help.
