What do you know about Rainbows?

Question

I'm looking for any information you can give me in regards to the formation, colors, ect. about rainbows.
Or any websites that have good information on rainbows.

Answer 1

The creation of a rainbow does actually follow various laws of physics that a scientist named Descartes began seriously investigating as far back as the 17th century. The formula involves variables like refraction and reflection of light, prisms, colour spectrums, antisolar points, and various other complicated-sounding words. But in reality, the formation of a rainbow is a rather simple science as long as all the variables are present at the moment of its creation.



Light is comprised of a series of colours: red, orange, yellow, green, blue, indigo and violet, not to mention other light, like ultraviolet, which is not as easily detected by the human eye. Light also has varying wavelengths. The longest wavelengths are visible to the human eye as the colour red, the shortest wavelength the colour violet, with a short list of other colours in between. When light passes through anything it will bend, or become refracted light. No two objects have the same refractive index. When light passes through an object like the ornamental crystals many people have hanging in their windows, each colour created will bend according to its corresponding wavelength and then spread to form rainbow colours on an opposite wall.


The same process occurs when the sun peeks out from behind the clouds during or right after a rainstorm. Raindrops must still be present in the atmosphere to create a rainbow. Think of a each single raindrop as a tiny prism or crystal. As the sun’s rays catch and shine through the droplets and the light refracts, or bends, this highly concentrated light once again breaks up into its various wavelengths and then goes on to create a rainbow. The colours of a rainbow always appear in the same order, beginning at the outer edge: red, orange, yellow, green, blue and violet. Sometimes the light reflects twice off the inside of a raindrop, creating a second rainbow just above the first. But when this happens the colours will appear in the reverse order, red on the inside, and so on. The colours of a secondary rainbow are usually never as bright as those of the primary rainbow either.


Rain showers and thunderstorms are not the only time rainbows occur. They may be observed in banks of fog or mist,in the spray that billows up from waterfalls or that’s created by lawn sprinklers or in any instance where light reflects through water or an object like a glass or a crystal. To see a rainbow in such an instance depends mostly on where the observer is standing. The light from the full moon can even create rainbows on the odd occasion, although these “lunary rainbows” are not seen nearly as often as those created by light from the sun.

Answer 2

The science of a rainbow is easy to find. Any search engine will return a ton of hits.

My personal thing about them is they are the only thing I know of that is one sided. A rainbow is only visible on the front, it has no back, sides, top or bottom.

I was hooked on Robert Heinlein for a while. He used the example in one of his books. It has just stuck with me.

Answer 3

The seven colours of the rainbow are - indigo, violet, yellow, blue, orange, red and green.

Cupcakes are consistently particular to a guy lol. i understand it ought to sound tacky in spite of the indisputable fact that it really is a lot more effective female to make cupcakes in my opinion. they imagine it really is stunning. pass with the funfetti cake, it really is the superb!

Answer 5

What do I know - they are wonderful to watch!
