I took this picture of rainbows near Apollo Bay a while ago.
Apollo Rainbow.jpg
Not understanding the phenomena that much, I did some Googling.
Actually the mechanics of rainbows are a bit too technical for me to understand and I am not going to try to explain what I read.
But some simplifications are within my capabilities.
Rainbows are formed when sunlight is refracted by water droplets - it can be any water source such as a hose or waterfall, but its usually associated with rain. The sun has to be behind you when you observe the rainbow & the optimum is when the sun is lower in the sky.
In the pic above, there are 2 rainbows..
The primary one on the left is the standard version where the colours are refracted in order of violet (lowest wavelength) to red (highest wavelength).
The secondary rainbow arises when light is refracted twice within the raindrops - and its always fainter & the colour spectrum is in reverse order!
Another interesting thing is that the rainbow effect makes the sky under the arc look substantially paler than the rest of the sky.
