Respuesta :

The bending of waves around a barrier or through a slit is called ( D ) ; Diffraction

Diffraction is the term used to describe the situation/phenomena whereby waves ( radio or cell signals ) emanating from an antenna is bent around obstacles between the antenna and the signal receiver.

Diffraction of waves is usually caused by the interference of waves with itself due to the presence of an obstacle. in order to get to the intended receiver the waves bends around the barrier through diffraction after constructive interference within itself.

Hence we can conclude that the bending of waves around a barrier or through a slit is known as diffraction
