Rainbow

How many colours do you see in a rainbow? I learned that there are seven when I was a little girl. The colours are red, orange, yellow, green, blue, indigo and purple. Since then I try to see those colours in the rainbow.

The truth is, there is no set number of colors in a rainbow! Each hue blends into the next without a hard boundary, leaving the interpretation up to the person who sees it and the culture that has defined it.

The Telegraph explains the magic as such: "Each raindrop acts as a tiny, imperfect mirror. When the sun is right behind you its light passes through the raindrops in front of you, reflects off their rear surface and bounces back at you. The light is refracted or “bent” slightly as it passes from the air into the water; and again as it bounces back into the air again. The different wavelengths that combine to make daylight are “bent” by different amounts (42º for the red end of the spectrum, a shade less for the violet). Each raindrop acts as both prism (refraction) and mirror (reflection)."
Great rainbow capture.
