Abstract

If the waves protrayed in Figure 1.15 had been single-wavelength light waves, rather than sound waves, and if the two radiators had been long slits perpendicular to the paper, a white screen placed to the right of these slits would have displayed a comparable series of bright and dark vertical bands, called, in optical terminology, fringes. We noted earlier, in connection with Figure 1.2, that when one of two wave sets is a full wavelength ahead of the other, the two again add, and, therefore, as in Figure 2.16, wave energy is diffracted into those off-angle directions for which such a condition holds.
