If ocean waves strike the shore every 3 s and the horizontal distance between adjacent crests and troughs is 1 m, what is the average speed of the waves?
A. 0.33
B 0.66
C
D
I realize how/why the answer is what it is. BUT...
Did anyone else interpret this as the distance between adjacent troughs = 1m? I think the wording here ambiguous and lead to a really worthless mistake. Mid-exam I thought the same thing... "which do they mean?". I ended up going with the distance between troughs (an entire wavelength) being 1 m rather than the difference from crest to trough being 1m. Just wondering if this was glaringly obvious to others or not.
