Rainbow
Rain"bow`\, n. [AS. regenboga, akin to G. regenbogen. See Rain, and Bow anything bent,] A bow or arch exhibiting, in concentric bands, the several colors of the spectrum, and formed in the part of the hemisphere opposite to the sun by the refraction and reflection of the sun's rays in drops of falling rain. Note: Besides the ordinary bow, called also primary rainbow, which is formed by two refractions and one reflection, there is also another often seen exterior to it, called the secondary rainbow, concentric with the first, and separated from it by a small interval. It is formed by two refractions and two reflections, is much fainter than the primary bow, and has its colors arranged in the reverse order from those of the latter. Lunar rainbow, a fainter arch or rainbow, formed by the moon. Marine rainbow, or Sea bow, a similar bow seen in the spray of waves at sea. Rainbow trout (Zo["o]l.), a bright-colored trout (Salmoirideus), native of the mountains of California, but now extensively introduced into the Eastern States. Japan, and other countries; -- called also brook trout, mountain trout, and golden trout. Rainbow wrasse. (Zo["o]l.) See under Wrasse. Supernumerary rainbow, a smaller bow, usually of red and green colors only, sometimes seen within the primary or without the secondary rainbow, and in contact with them.Cite This Source

rainbow (rān'bō') Pronunciation Key
(click for larger image in new window) An arc-shaped spectrum of color seen in the sky opposite the Sun, especially after rain, caused by the refraction and reflection of sunlight by droplets of water suspended in the air. Secondary rainbows that are larger and paler sometimes appear within the primary arc with the colors reversed (red being inside). These result from two reflections and refractions of a light ray inside a droplet. |

Rainbow
caused by the reflection and refraction of the rays of the sun shining on falling rain. It was appointed as a witness of the divine faithfulness (Gen. 9:12-17). It existed indeed before, but it was then constituted as a sign of the covenant. Others, however (as Delitzsch, Commentary on Pentateuch), think that it "appeared then for the first time in the vault and clouds of heaven." It is argued by those holding this opinion that the atmosphere was differently constituted before the Flood. It is referred to three other times in Scripture (Ezek. 1:27, 28; Rev. 4:1-3; 10:1).
