obstacle with size close to its wavelength (Fig 1). Diffraction refers to various phenomena that occur when a wave encounters an obstacle or opening. Diffraction occurs when a wave stays in the same medium, but bends around an obstacle. diffraction: The bending of a wave around the edges of an opening or an obstacle. It is defined as the bending of waves around the corners of an obstacle or through an aperture into the region of geometrical shadow of the obstacle/aperture. When a wave encounters a small obstacle or a small opening (that is, small compared with the wavelength of the wave), the wave can bend around the obstacle or pass through the opening and then spread out. This bending or spreading out is called diffraction. An instrument called a spectrometer uses diffraction to separate light into a range of wavelengths—a spectrum.
