Diffraction
Explnation":The bending of waves around obstacle in its path is called diffraction.
When a sound wave bends around a barrier whose dimensinn is lesser than or equal to its wavelength, this phenomenon is referred to as diffraction.
The sound can be heard even though the source of the sound cannot be seen. e
