  2. Brewster's angle - Wikipedia

    en.wikipedia.org/wiki/Brewster's_angle

    Brewster's angle is often referred to as the "polarizing angle", because light that reflects from a surface at this angle is entirely polarized perpendicular to the plane of incidence ("s-polarized"). A glass plate or a stack of plates placed at Brewster's angle in a light beam can, thus, be used as a polarizer.

  3. WMF Group - Wikipedia

    en.wikipedia.org/wiki/WMF_Group

    WMF was originally called Metallwarenfabrik Straub & Schweizer and was opened as a metal repairing workshop. Through mergers and acquisitions, by 1900 they were the world's largest producer and exporter of household metalware, mainly in the Jugendstil, or Art Nouveau style, designed in the WMF Art Studio under Albert Mayer, sculptor and designer, who was director from 1884 to 1914.

  4. Iridescence - Wikipedia

    en.wikipedia.org/wiki/Iridescence

    Iridescence is an optical phenomenon of surfaces in which hue changes with the angle of observation and the angle of illumination. [ 2 ] [ 3 ] It is often caused by multiple reflections from two or more semi-transparent surfaces in which phase shift and interference of the reflections modulates the incidental light , by amplifying or ...

  5. Brewster angle microscope - Wikipedia

    en.wikipedia.org/wiki/Brewster_angle_microscope

    A Brewster angle microscope (BAM) is a microscope for studying thin films on liquid surfaces, most typically Langmuir films. In a Brewster angle microscope, both the microscope and a polarized light source are aimed towards a liquid surface at that liquid's Brewster angle , in such a way for the microscope to catch an image of any light ...

  7. Ideal surface - Wikipedia

    en.wikipedia.org/wiki/Ideal_surface

    An ideal solid surface is flat, rigid, perfectly smooth, and chemically homogeneous, and has zero contact angle hysteresis. Zero hysteresis implies the advancing and receding contact angles are equal. Figure 1: Contact angle for a liquid droplet on a solid surface. In other words, only one thermodynamically stable contact angle exists. When a ...

  8. Special right triangle - Wikipedia

    en.wikipedia.org/wiki/Special_right_triangle

    A special right triangle is a right triangle with some regular feature that makes calculations on the triangle easier, or for which simple formulas exist. For example, a right triangle may have angles that form simple relationships, such as 45°–45°–90°. This is called an "angle-based" right triangle.
