  2. Fog bow - Wikipedia

    en.wikipedia.org/wiki/Fog_bow

    A fog bow, sometimes called a white rainbow, [1] is a similar phenomenon to a rainbow; however, as its name suggests, it appears as a bow in fog rather than rain. [2] Because of the very small size of water droplets that cause fog—smaller than 0.05 millimeters (0.0020 in)—the fog bow has only very weak colors, with a red outer edge and ...

  3. Rainbow - Wikipedia

    en.wikipedia.org/wiki/Rainbow

    The secondary rainbow is fainter than the primary because more light escapes from two reflections compared to one and because the rainbow itself is spread over a greater area of the sky. Each rainbow reflects white light inside its coloured bands, but that is "down" for the primary and "up" for the secondary. [30]

  4. Visible spectrum - Wikipedia

    en.wikipedia.org/wiki/Visible_spectrum

    An example of this phenomenon is when clean air scatters blue light more than red light, and so the midday sky appears blue (apart from the area around the Sun which appears white because the light is not scattered as much). The optical window is also referred to as the "visible window" because it overlaps the human visible response spectrum.

    Most rainbows are colorful and vibrant, but not this one. A rare white rainbow, also known as a ghost rainbow or a fogbow, was captured on video arcing over the skies of Heihe, Heilongjiang ...

  7. Spectral color - Wikipedia

    en.wikipedia.org/wiki/Spectral_color

    A rainbow is a decomposition of white light into all of the spectral colors. Laser beams are monochromatic light, thereby exhibiting spectral colors. A spectral color is a color that is evoked by monochromatic light, i.e. either a spectral line with a single wavelength or frequency of light in the visible spectrum, or a relatively narrow spectral band (e.g. lasers).

  8. Dispersive prism - Wikipedia

    en.wikipedia.org/wiki/Dispersive_prism

    Photograph of a triangular prism, dispersing light Lamps as seen through a prism. In optics, a dispersive prism is an optical prism that is used to disperse light, that is, to separate light into its spectral components (the colors of the rainbow). Different wavelengths (colors) of light will be deflected by the prism at different angles. [1]

  9. Atmospheric optics - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_optics

    A rainbow is a narrow, multicoloured semicircular arc due to dispersion of white light by a multitude of drops of water, usually in the form of rain, when they are illuminated by sunlight. Hence, when conditions are right, a rainbow always appears in the section of sky directly opposite the Sun.
