If you were standing at the end of a pier with a stopwatch in hand, how would you measure the average WAVE PERIOD of the waves that pass by?
a. Determine a fixed point on the pier and note the time between a crest and trough that reaches that point.
b. Stand at the end of the pier and record the amount of time that it takes for a wave to break from the crest to its trough.
c. Stand at the end of the pier and record the distance from a wave's crest to its trough.
d. Determine a fixed point on the pier and note the time between a crest and the next crest that reaches that point.

Finding Wave Periods have NOTHING to do with the trough.

I'm pretty sure you and I are in the same class given I JUST answered that question about a day ago
