When light shines through water drops in the sky, rainbows appear. Most often when you have both rain and sunshine, like here shortly after a rain shower.

Sometimes you can see two rainbows at once. The light being reflected inside the raindrop causes the primary rainbow. But not all of the ray escapes the raindrop after it is reflected once. A part of the ray is reflected again and travels along inside the drop to emerge from the drop. The secondary rainbow arises from two internal reflections and the rays exit the drop at an angle of 50 degrees rather than the 42 degrees for the primary rainbow.

Run for the pot of gold at the end of the rainbow. Well, seeing this rainbow the legend would be easy to follow, its rays ending right there in front of the trees. Both pics are from the same rainbow.

Not only rainy skies are filled with water drops. Rainbows also appear in your garden in water sprinklers, but also at waterfalls like here at the magnificent Iguazu Falls.

Another world famous waterfall is the Victoria Falls on the border between Zimbabwe and Zambia. The water levels in the year 2000 were extremely high which produced a lot of water spray. Note the secondary bow.

How about this perfect twin image of the bridge over the Zambezi river. Makes you wonder if the bridge designer had something special in mind.

A cool pic where a rainbow is formed when working with the garden hose.
