In our discussion of waves on springs, we did "the wave" in class, with people jumping up from their seats one after the other.   Was this analogy of any use in helping us make sense of what was happening when a pulse moves on an elastic spring?   If your answer is yes, explain why you think so and give one example of a concept, principle, or issue concerning wave motion that is clarified by the analogy.   If your answer is no, discuss what the lecturer was trying to do with the analogy and explain why it did not help you.
