10106061011304DiffractionDiffraction and interference are the same phenomenon, and it is unfortunate that two different terms are used. Both involve the interaction (interference) of two waves. These effects occur for all waves, not just light. The term diffraction is used when light passes through a single opening or next to an opaque object and one part of the wave front interferes with another part of the same wavefront. Because of the wave nature of light and the spreading out of secondary waves, the shadow of something like a razor blade is not sharply defined. Instead, the edge of the shadow is a series of closely spaced light and dark regions. These are very closely spaced and…
