2. Diffraction from slits - Wikipedia

   en.wikipedia.org/wiki/Diffraction_from_slits

   Because diffraction is the result of addition of all waves (of given wavelength) along all unobstructed paths, the usual procedure is to consider the contribution of an infinitesimally small neighborhood around a certain path (this contribution is usually called a wavelet) and then integrate over all paths (= add all wavelets) from the source to the detector (or given point on a screen).

4. N-slit interferometer - Wikipedia

   en.wikipedia.org/wiki/N-slit_interferometer

   The N-slit interferometer is an extension of the double-slit interferometer also known as Young's double-slit interferometer. One of the first known uses of N-slit arrays in optics was illustrated by Newton. [1] In the first part of the twentieth century, Michelson [2] described various cases of N-slit diffraction.

5. Double-slit experiment - Wikipedia

   en.wikipedia.org/wiki/Double-slit_experiment

   Same double-slit assembly (0.7 mm between slits); in top image, one slit is closed. In the single-slit image, a diffraction pattern (the faint spots on either side of the main band) forms due to the nonzero width of the slit. This diffraction pattern is also seen in the double-slit image, but with many smaller interference fringes.

6. Fraunhofer diffraction equation - Wikipedia

   en.wikipedia.org/wiki/Fraunhofer_diffraction...

   Geometry of two slit diffraction Two slit interference using a red laser. Assume we have two long slits illuminated by a plane wave of wavelength λ. The slits are in the z = 0 plane, parallel to the y axis, separated by a distance S and are symmetrical about the origin. The width of the slits is small compared with the wavelength.

7. Diffraction - Wikipedia

   en.wikipedia.org/wiki/Diffraction

   When the diffracting object has a periodic structure, for example in a diffraction grating, the features generally become sharper. The third figure, for example, shows a comparison of a double-slit pattern with a pattern formed by five slits, both sets of slits having the same spacing, between the center of one slit and the next.

8. Fraunhofer diffraction - Wikipedia

   en.wikipedia.org/wiki/Fraunhofer_diffraction

   Graph and image of single-slit diffraction. The width of the slit is W. The Fraunhofer diffraction pattern is shown in the image together with a plot of the intensity vs. angle θ. [10] The pattern has maximum intensity at θ = 0, and a series of peaks of decreasing intensity. Most of the diffracted light falls between the first minima.

9. Lloyd's mirror - Wikipedia

   en.wikipedia.org/wiki/Lloyd's_mirror

   In Young's experiment, the individual slits display a diffraction pattern on top of which is overlaid interference fringes from the two slits (Fig. 2). In contrast, the Lloyd's mirror experiment does not use slits and displays two-source interference without the complications of an overlaid single-slit diffraction pattern.
