Pepe and Alfredo are resting on an offshore raft after a swim they estimate that 3.0 m separates trough adjacent crest of each surface wave the lake?
The wavelength of a wave is the distance between two adjacent crests or two adjacent troughs. In this case, Pepe and Alfredo estimate that the distance between two adjacent crests of each surface wave is 3.0 m, so this must be the wavelength.
