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).

3. X-ray diffraction - Wikipedia

   en.wikipedia.org/wiki/X-ray_diffraction

   Barkla created the x-ray notation for sharp spectral lines, noting in 1909 two separate energies, at first, naming them "A" and "B" and, supposing that there may be lines prior to "A", he started an alphabet numbering beginning with "K." [2] [3] Single-slit experiments in the laboratory of Arnold Sommerfeld suggested that X-rays had a ...

4. Quantum eraser experiment - Wikipedia

   en.wikipedia.org/wiki/Quantum_eraser_experiment

   This experiment involves an apparatus with two main sections. After two entangled photons are created, each is directed into its own section of the apparatus. Anything done to learn the path of the entangled partner of the photon being examined in the double-slit part of the apparatus will influence the second photon, and vice versa.

5. Wavelength - Wikipedia

   en.wikipedia.org/wiki/Wavelength

   In the analysis of the single slit, the non-zero width of the slit is taken into account, and each point in the aperture is taken as the source of one contribution to the beam of light (Huygens' wavelets). On the screen, the light arriving from each position within the slit has a different path length, albeit possibly a very small difference.

6. Diffraction - Wikipedia

   en.wikipedia.org/wiki/Diffraction

   Graph and image of single-slit diffraction. A long slit of infinitesimal width which is illuminated by light diffracts the light into a series of circular waves and the wavefront which emerges from the slit is a cylindrical wave of uniform intensity, in accordance with the Huygens–Fresnel principle.

7. List of optics equations - Wikipedia

   en.wikipedia.org/wiki/List_of_optics_equations

   Visulization of flux through differential area and solid angle. As always ^ is the unit normal to the incident surface A, = ^, and ^ is a unit vector in the direction of incident flux on the area element, θ is the angle between them.

8. Lloyd's mirror - Wikipedia

   en.wikipedia.org/wiki/Lloyd's_mirror

   Lloyd's mirror has important advantages over double-slit interferometers. If one wishes to create a series of closely spaced interference fringes using a double-slit interferometer, the spacing d between the slits must be increased. Increasing the slit spacing, however, requires that the input beam be broadened to cover both slits.

9. 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.
