(b) Diffraction refers to various phenomenon associated with wave propagation, such as bending spreading and interference of waves emerging from aperture. While diffraction always occurs its effects are generally only noticeable for waves where the wavelength is of the order of the feature size of the diffraction objects or apertures. |
