  2. Lecture 12: Fraunhofer diffraction by a single slit Lecture aims to explain: 1. This gave great support to the wave theory of light that had been.
  3. Light passing through a single slit forms a diffraction pattern somewhat different from those formed by double slits or diffraction gratings, which we discussed in the chapter on interference. (Figure) shows a single-slit diffraction pattern.

SINGLE SLIT DIFFRACTION PATTERN OF LIGHT. The diffraction pattern observed with light and a small slit comes up in about every high school and first.

The web lesson for this is pretty light and consists mostly of links toother websites. There are some important things to note about both diffraction gratings and single slits. Diffraction gratings may be treated exactly the same as a double slit problem. In otherwords,

What makes the diffraction grating unique is that you get very definedmaxima and minima due to the effect of multiple slits that are very close together. To figure the distance, d, between the slits, simply take the inverse of the diffraction lines in meters. Forexample, if a grating has 10,000 scratches per .01 m, then the distance between slits is .01m/10,000 = 1 x 10-6 meters.

Single Slit problems, on the other hand, are a bit different. Light isbending around a single slit and the wavelets essentially interfere with themselves. As such, you get a very pronounced central maxima that is twice as wide as the other maxima in a single slit. Theformula for finding the location of the maxima for single slits is:

where m is the order of magnitude, D is the width of the slit in meters,andqis the angle between the center of the central maxima and the first minima. By the way, insingle slits, minima occur at the integer multiples of the wavelength. This is exactly the opposite of what happens with double slits.
