Universal entry(ies)
Cu9Fe9S16
formula, see observation
DEF

Tetragonal sulfide of iron and copper.

CONT

Under reflected light mooihoekite and haycockite have a color similar to that of chalcopyrite in a freshly polished section. Mooihoekite tarnishes, however, on exposure to air through different hues of pinkish brown to a heavy purplish color but at a rate slower than that reported for talnakhite.... Mooihoekite is weakly anisotropic, whereas haycockite is weakly to moderately anisotropic.

Subject field(s)
  • Atmospheric, Climatic and Meteorological Phenomena
DEF

Rainbow formed in the same way as the solar rainbow, but with light from the Moon rather than the Sun.

CONT

A night time rainbow is sometimes called a moon bow because it is a reflection of the light of the moon.... Any rainbow comes from light hitting drops of rain and going into the drop and being reflected off of the inside edge. As the light leaves the drop on it's return journey the other side of the drop acts like a prism and separates it into the colors of the rainbow.... with moon light it makes something shaped like a rainbow with just a hint color. Moon bows occur in the side of the sky opposite the moon.

OBS

Even though the optics of both is the same, the luminance of the lunar rainbow is much lower. As a result of the eye’s reduced sensitivity to color at low light levels, the bow may exhibit little color. There are several reasons why the lunar rainbow is seen much less frequently than the solar bow. While the moon and sun spend equal time above the horizon, when they are both present, only a solar bow can be seen. This, by itself, means that the lunar rainbow could form only half as often. Further, the moon goes through phases, and so even at night may not contribute enough light to produce a discernible bow. Finally, the convective showers in which the rainbow is frequently seen are much less common at night.

DEF

Arc-en-ciel formé de la même façon que l'arc-en-ciel solaire, mais dont la lumière provient de la Lune et non du Soleil.

CONT

Beaucoup plus rare et bien moins spectaculaire, l'arc-en-ciel lunaire est pour le reste similaire à l'arc-en-ciel solaire. C'est un arc [très peu] coloré [ordinairement blanchâtre, très peu d'auteurs disent y avoir distingué une ou deux couleurs] qui ne se présente qu'à l'observateur qui tourne le dos à la Lune [...]

Subject field(s)
  • Physics

  • Meteorology
CONT

Why is the sky blue?... Scattering, simply defined, is when light hitting a volume of air is reflected out of the air, as opposed to being absorbed or just passing through. The light bounces off of individual air particles in random directions, scattering, and making that air appear the color of the light being scattered. Preferential light scattering means that some colors of light scatter better, while other colors tend only to pass through. Lord Rayleigh, a 19th century British physicist, first explained preferential light scattering.(Sir Isaac Newton first established the phenomenon's existence.) Common air particle diameters are 1 micron(micrometer),. 1 micron, and. 01 micron.... "Rayleigh's Law indicates that the light energy scattered per unit volume of air containing particles smaller than. 1 micron is inversely proportional to the 4th power of the wavelength of the illuminating radiation(Schaeffer 155) "... More simply stated, the amount of light that bounces around in our air increases as the wavelength(which is related to color) of the light decreases.

CONT

Selon la loi de Rayleigh, la diffusion moléculaire est proportionnelle à l'inverse de la quatrième puissance de la longueur d'onde [...]; la couleur bleue du ciel est due à ce phénomène.
