Describe and explain the Fraunhoffer diffraction pattern obtained with narrow slit and illuminated by parallel beam of monochromatic light.

Find the half angular width of the central bright maximum in the fraunhofer diffraction pattern of a slit of width 12xx10^(-5)cm when the slit is illuminated by monochromatic light of wavelength 6000 Å.

Use Huygens's principle to explain the formation of diffraction pattern due to a single slit illuminated by a monochromatic source of light. When the width of the slit is made double the original width, how would this affect the size and intensity of the central diffraction band ?
