Answer
Diffraction occurs when a wave encounters an obstacle or a slit that is approximately the same size as its wavelength. The wave bends around the slit. The diffraction of light through two slits separated by a distance comparable to the wavelength of the light results in an interference pattern. Each slit works as a new wave source, and the two new waves interfere with each other. The result is a pattern of bright and dark lines.
