I Laser diffraction through single slit

  1. Mar 29, 2016 #1
    Will a laser diffract through a single slit if the laser beam width is smaller than the slit? Such that the laser beam can pass though without touching the sides.

    There is practically no diffraction in such a configuration.

    Example: shine a laser beam (e.g. from a laser pointer) through the center of an open doorway.

    The laser exit itself is like a single slit already, and you see its effect: you don't see its diffraction (for most lasers).
