Chapter 7 starts by providing some simple observations of light diffraction—the reciprocal relation between the diffracting object and diffraction pattern. It then looks at the nature of light as explained by Newton and Huygens. It gives two concepts of coherence, scattering, and interference. The chapter provides an analysis of the geometry of diffraction patterns from gratings and nets by looking at principal and subsidiary maxima. It outlines Young's slits experiments and the diffraction-limited resolving power of optical instruments relating to the telescope, microscope, camera, and the eye.
