DIFFRACTION,ANGULAR RESOLUTION AND MORE

Description
It starts with grating but later an experiment shows single slit diffraction .In it he shows an incredible experiment where as the slit width decreases the width of the central maxima increases--in accordance with the theory. In the later half angular resolution is discussed and how diffraction limits angular resolution of our eye has been explained.
