Question 1052Navigation General
70% to passThe length of a wave is the length _______________.
A
of the wave's crest
B
measured from crest to trough
C
of the wave's trough
D
measured from crest to crest
AI Explanation
The correct answer is D) measured from crest to crest. The length of a wave is defined as the distance between two consecutive wave crests, or the horizontal distance between two successive wave crests. This is the standard definition of wave length in the context of maritime operations and Coast Guard licensing examinations. The other answer choices are incorrect because they do not accurately describe the measurement of wave length. The length of the wave crest (A) or trough (C) would not be the full wave length. Measuring from crest to trough (B) would only give the height of the wave, not the full wave length.
