The three-dimensional phenomenon resulting from a attenuation of agitation, due to the presence of obstacles, is responsible for the propagation of waves in the geometric shadow zones, referred to the direction of the waves, and can be treated analogously to what is known with the propagation of electromagnetic waves. The energy transferred along the wave fronts, transversely to the orthogonal ones, with a speed equal to that of the wave, is known as:


A) breakwater;
B) refraction;
C) diffraction;
D) longitudinal currents;
E) reflection.
