(Each ray is perpendicular to the wavefront of a wavelet.) Assuming the screen is very far away compared with the size of the slit, rays heading toward a common destination are nearly parallel. These are like rays that start out in phase and head in all directions. According to Huygens’s principle, every part of the wavefront in the slit emits wavelets. Here we consider light coming from different parts of the same slit. The analysis of single slit diffraction is illustrated in Figure 2. (b) The drawing shows the bright central maximum and dimmer and thinner maxima on either side. The central maximum is six times higher than shown. Monochromatic light passing through a single slit has a central maximum and many smaller and dimmer maxima on either side. In contrast, a diffraction grating produces evenly spaced lines that dim slowly on either side of center. Note that the central maximum is larger than those on either side, and that the intensity decreases rapidly on either side. Figure 1 shows a single slit diffraction pattern. Light passing through a single slit forms a diffraction pattern somewhat different from those formed by double slits or diffraction gratings. Discuss the single slit diffraction pattern.Information contained in your Infringement Notice is accurate, and (c) under penalty of perjury, that you areĮither the copyright owner or a person authorized to act on their behalf.

In the above equation, represents the wavelength of light, represents the length of the slit, and represents the location of the dark fringes (it can equal ). We're then asked to determine the wavelength of the light based on this information.įirst and foremost, we'll need to use the light diffraction equation: In this question, we're told that the size of the slit is, and the first of these dark fringes occurs at an angle of away from the slit. In such a case, there will be a central bright fringe, with alternating dark and bright fringes as one moves above and below the central fringe. In doing so, the light is diffracted, meaning that it is spread out along a viewing screen. For this question, we're presented with a scenario in which light is passing through a small slit.
