When waves moving towards the beach, the shape of the wavefronts will take on the contours of the beach as the waves get closer to it.
This phenomenon is due to
diffraction
reflection
refraction
interference
What is diffraction?
Diffraction is the change in the direction of the waves
Diffraction is an increase in the speed of the waves
Diffraction is the spreading of waves when it passes through an aperture or round a small obstacle.
