A water break at the entrance to a harbor consists of a rock barrier with a 74.0 m wide opening. Ocean waves of 35.1 m wavelength approach the opening straight on. At what angle to the incident direction are the boats inside the harbor most protected against wave action

Explanation:

From the question we are told that:

Width of opening

Wavelength

Generally the equation for Angle is mathematically given by

Since the ocean diffracts

Therefore the relation

Where

n =nth order minimal (n=1 for smallest safe angle)

Therefore

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).
