  2. Rainbow - Wikipedia

    en.wikipedia.org/wiki/Rainbow

    A rainbow is an optical phenomenon caused by refraction, internal reflection and dispersion of light in water droplets resulting in a continuous spectrum of light appearing in the sky. [1] The rainbow takes the form of a multicoloured circular arc . [ 2 ]

  3. Atmospheric optics - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_optics

    Rainbows. These result from a combination of internal reflection and dispersive refraction of light in raindrops. Because rainbows are seen on the opposite side of the sky from the Sun, rainbows are more visible the closer the Sun is to the horizon. For example, if the Sun is overhead, any possible rainbow appears near an observer's feet ...

  4. Optical phenomenon - Wikipedia

    en.wikipedia.org/wiki/Optical_phenomenon

    Optical phenomena encompass a broad range of events, including those caused by atmospheric optical properties, other natural occurrences, man-made effects, and interactions involving human vision (entoptic phenomena).

  5. Refraction - Wikipedia

    en.wikipedia.org/wiki/Refraction

    In physics, refraction is the redirection of a wave as it passes from one medium to another. The redirection can be caused by the wave's change in speed or by a change in the medium. [1] Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction. How much a wave ...

    They look like retro, faded rainbows that stayed out in the sun too long and lost their color. Well, after a fogbow was spotted in Tulsa, the chief meteorologist at our partner.

    Articles relating to the rainbow, a meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. It takes the form of a multicoloured circular arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the Sun.

    The 46° halo was first explained as being caused by refractions through ice crystals in 1679 by the French physicist Edmé Mariotte (1620–1684) in terms of light refraction [1] Jacobowitz in 1971 was the first to apply the ray-tracing technique to hexagonal ice crystal. Wendling et al. (1979) extended Jacobowitz's work from hexagonal ice ...

  9. Circumhorizontal arc - Wikipedia

    en.wikipedia.org/wiki/Circumhorizontal_arc

    A circumhorizontal arc is an optical phenomenon that belongs to the family of ice halos formed by the refraction of sunlight or moonlight in plate-shaped ice crystals suspended in the atmosphere, typically in actual cirrus or cirrostratus clouds. In its full form, the arc has the appearance of a large, brightly spectrum-coloured band (red being ...
