Diffraction of water waves

Let vibrator produce circular wavefronts travelling along (P).
Let X, Y be two vertical glass plates immersed in the tank far away from the vibrating source S, such that there is an opening AB between them.
Then, a plane wavefront MN would be incident on AB where the edges A and B act as obstacles. Any opening such as AB is called an ‘aperture'.
The portion of the wavefront incident on AB escapes through the aperture and results in a number of circular wavefronts which spread out in all directions as if they have originated in the aperture AB.
The waves emerging from AB deviate from their original direction of propagation along P and travel along other directions like Q and R.
The formation of circular wavefronts and their propagation in a direction different from the original direction is due to ‘bending' of the waves.
This phenomenon is called ‘diffraction'. (Refer text book for diagram )
