5.5 DYNAMIC THEORY 2

Question 1

What is a progressive wave?

Answer 1

The disturbance produced in the medium is handed over from one particle to the next. Each particle executes the same type of vibration as the preceding one, though not at the same time.

In the real world, tides can’t propagate endlessly as progressive waves They undergo reflection at sudden depth changes and at coastal boundaries. Reflective and incident waves come together to give the observed wave.
