Diffraction The property of light to bend as it passes around an obstacle or narrow slit, causing the light to spread and to produce light and dark fringes is call diffraction. Diffraction is more pronounced through relatively small openings when the light wavelength is comparable with the size of a slit or an object . 2 Example: Diffraction of radio waves . Why the reception of AK radio waves is usually better than FK waves?...
