  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).

    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.

  4. 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.

  5. Diffraction - Wikipedia

    en.wikipedia.org/wiki/Diffraction

    A diffraction pattern of a red laser beam projected onto a plate after passing through a small circular aperture in another plate. Diffraction is the interference or bending of waves around the corners of an obstacle or through an aperture into the region of geometrical shadow of the obstacle/aperture.

  6. 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.
