The dark fringes are regularly spaced, in exactly the manner described by Equation 2.4.3 (note: sin y L sin. The intensity of the central maximum will increase because the photons are less spread out. The light will just pass straight through without being diffracted at all. This is because the diffraction effects will decrease. Lets point out a few of the more prominent features of this intensity pattern. If we increase the slit width, the width of the central maximum will decrease. One way to think of this is to go back to the diffraction grating case, expressed in Equation 3.3.2. A graph of the intensity of the full interference pattern looks like this: Figure 2.4.3 - Single Slit Diffraction Intensity.

To compute the intensity of the interference pattern for a single slit, we treat every point in the slit as a source of an individual Huygens wavelet, and sum the contributions of all the waves coming out at an arbitrary angle. Significantly more math is required to deal with the intensity of the bright fringes. The two slits are separated by a distance d. In the experiment a particles path through the slits is determined by measuring the Coulomb field that it produces at large distances under these conditions. Figure 14.2.3 Double-slit experiment Consider light that falls on the screen at a point P a distance from the point O that lies on the screen a perpendicular distance L from the double-slit system.

Coherent light passing through six (6) slits separated by a distance d produces a pattern of dark and bright areas on a distant screen. The geometry of the double-slit interference is shown in the Figure 14.2.3. Experimentation reveals that an interference pattern occurs when light passes through a single slit.

Realistic Double-Slit Diffraction Okay, now let’s return. This phenomenon is known as Babinets principle. The bright fringes only approximately follow the same spacing pattern, not exactly located halfway between the dark fringes, but using the pairwise approach doesn't tell us much about the intensity of those bright regions, for the same reason it didn't for the central bright fringe – constructive pairs will not be in phase with other constructive pairs.

This takes into account both the difference in optical path length for the two rays and the 180 phase change For destructive interference d2t mn (m 0, 1.
