SUMMARY
Diffraction effects become noticeable when the size of an obstacle is comparable to the wavelength of radiation. This is due to the interaction of waves with the edges of the obstacle or aperture. For openings much smaller than the wavelength, radiation interacts through phenomena such as Fresnel diffraction and knife edge diffraction, which illustrate how waves propagate around obstacles. The principles of diffraction also apply to phonons in crystal lattices and mechanical waves on strings, confirming the universality of these wave behaviors.
