2. File:Diffraction of plane wave from plasmonic slit.png

   en.wikipedia.org/wiki/File:Diffraction_of_plane...

   Diffraction of a plane wave (with 632.8 nm wavelength) from a plasmonic slit with a width and depth of 200 and 300 nm, respectively. The simulation was performed by open-source FDFD solver, MaxwellFDFD.

3. 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. 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.

5. Fraunhofer diffraction equation - Wikipedia

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

   Diffraction geometry, showing aperture (or diffracting object) plane and image plane, with coordinate system. If the aperture is in x ′ y ′ plane, with the origin in the aperture and is illuminated by a monochromatic wave, of wavelength λ, wavenumber k with complex amplitude A(x ′,y ′), and the diffracted wave is observed in the unprimed x,y-plane along the positive -axis, where l,m ...

6. Diffraction - Wikipedia

   en.wikipedia.org/wiki/Diffraction

   Diffraction is the same physical effect as interference, but interference is typically applied to superposition of a few waves and the term diffraction is used when many waves are superposed. [1]: 433 Italian scientist Francesco Maria Grimaldi coined the word diffraction and was the first to record accurate observations of the phenomenon in 1660.

7. 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.

8. 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.

9. 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.
