white rainbow (mist rainbow)
A white bow, the morning in the north/the Society for the Protection of Nature, Nadav Israeli
Nadav Israeli, a birder with the Society for the Protection of Nature and a resident of the Galilee, recorded this morning (Thursday) an elusive, special and rare phenomenon - a rainbow of fog, white in color.
As the name suggests, this is a phenomenon very similar to the colorful rainbow we know, but is formed in fog rather than rain.
Because of the very small size of the water droplets in the fog - less than 0.05 millimeters - the colors in such a rainbow are very weak and you can see mainly the color white, with a little red on the outside and a little blue on the inside.
In a normal arc, the water drops "break" the light into its colors, and each color is returned to us at a slightly different angle.
In the fog application the water drops are small enough and close to each other so that the colors "mix" again and return to shine on us with white light.
The exact same thing happens in the clouds, and therefore they are also white.
