APOD 4.5

This image, "A Hall of Mountain Glory" is very interesting and vibrant to behold. The picture itself depicts a very strange phenomenon, which is 3 rainbows almost one on top of the other, in a misty mountain area. However, the mist in this picture is actually a very odd optical illusion that is created by the air in the area. Light is being backscattered off of a cloud passing below the peak of a mountain. The 'fog' itself, would actually seem to dissipate, if one tried to walk through it and experience it. The refraction, reflection, and diffraction of Sunlight on water droplets in the air, is what causes this. While perusing the relevant links in the article, I learned two very different things. One, is that such phenomenons are often called 'Broken Spectres', and also that 'In The Hall of the Mountain King', an orchestral piece which I have heard before, was composed by Edvard Grieg.
