Diffraction of water waves, Physics

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 )
