How is a rainbow formed? What is it made up of, and can you ever really find the end of it?
And what's all this nonsense about a pot of gold where did that originate?
Answers:
Rainbows don't exist. What you can see is the light from the sun (behind you) relected and refracted by raindrops. You can't go there - what you see would move with you.
You can only see a rainbow where there are raindrops. It seems to end where it touches the ground, but that's because there aren't any raindrops down there. If you could get high enough, you would be able to see the whole circle - so there's no end.
its light being split when it passes through air or rain not sure but i think no you cant find the end as its a visual illusion and there is no end
Not sure where it originated from but its nonsense. Its formed of white light being split, like a spectrum of colours. Think of the dark side of the moon album cover, similar principle. You can't find the end because when you get there, you will be at the beginning again, because as you move, the rainbow will move, like if you tried walking towards the sun or moon in hope that you could eventually touch it.
A rainbow is formed when the sun's light passes through millions of drops of rain, which act like a prism and split the light into a spectrum of colours, which we see as a rainbow.
Its only a bow from the ground, as it disappears behind the horizon. In actual fact it is a complete circle, which is what you'd see from above.
A rainbow is an optical and meteorological phenomenon that causes a nearly continuous spectrum of light to appear in the sky when the Sun shines onto droplets of moisture in the Earth's atmosphere. It takes the form of a multicoloured arc, with red on the outside and violet on the inside. A double rainbow includes a second, fainter, arc with colors in the opposite order.
The rainbow has a place in legend due to its beauty and the difficulty in explaining the phenomenon before the work of Descartes in the 17th century (although, as mentioned above, Theodoric of Freiburg had given a satisfactory explanation in the 13th century.)
In Greek mythology, the rainbow was considered to be a path made by a messenger (Iris) between Earth and Heaven. In Chinese mythology, the rainbow was a slit in the sky sealed by Goddess Nüwa using stones of five different colours. In Hindu mythology, the rainbow is called Indradhanush, meaning the bow of Indra, the God of lightning and thunder. In Norse Mythology, a rainbow called the Bifröst Bridge connects the realms of Ásgard and Midgard, homes of the gods and humans, respectively. The Irish leprechaun's secret hiding place for his crock of gold is usually said to be at the end of the rainbow (which is impossible to reach). In the Hebrew Bible, the rainbow is a symbol of the covenant between God and man, and God's promise to Noah that he would never again flood the entire Earth. The Rainbow has even become the symbol for a modern movement within Judaism called B'nei Noah. B'nei Noah are non-Jews who continue to follow in the ways of their ancestor Noah. The Noahide movement has its roots in Jewish Tradition, specifically the Talmud.
Even though a rainbow spans a continuous spectrum of colours, traditionally the full sequence of colours is most commonly cited as red, orange, yellow, green, blue, indigo and violet. It is commonly thought that indigo was included due to the different religious connotations of the numbers six and seven at the time of Isaac Newton's work on light, despite its lack of scientific significance and the poor ability of humans to distinguish colours in the blue portion of the visual spectrum.
The rainbow effect can be observed whenever there are water drops in the air and sunlight shining from behind the observer at a low altitude or angle. The most spectacular rainbow displays when half of the sky is still dark with draining clouds and the observer is at a spot with clear sky overhead. The rainbow effect is also commonly seen near waterfalls or fountains. Rainbow fringes can sometimes be seen at the edges of backlit clouds and as vertical bands in distant rain or virga. The effect can also be artificially created by dispersing water droplets into the air during a sunny day.
In a very few cases, a moonbow, or night-time rainbow, can be seen on strongly moonlit nights. As human visual perception for colour in low light is poor, moonbows are most often perceived to be white.
The rainbow's appearance is caused by dispersion of sunlight as it is refracted by (approximately spherical) raindrops. The light is first refracted as it enters the surface of the raindrop, reflected off the back of the drop, and again refracted as it leaves the drop. The overall effect is that the incoming light is reflected back over a wide range of angles, with the most intense light at an angle of about 40°–42°. This angle is independent of the size of the drop, but does depend on its refractive index. As seawater has a higher refractive index than rain water, the radius of a 'rain'bow in a sea spray is smaller than a true rainbow. This is visible to the naked eye by a misalignment of these bows.
Since the water is dispersive, the amount that the sunlight is bent depends upon the wavelength, and hence colour, of the light's constituent parts. Blue light is refracted at a greater angle than red light, but because the area of the back of the droplet has a focal point inside the droplet, the spectrum crosses itself, and therefore the red light appears higher in the sky, and forms the outer colour of the rainbow. Contrary to popular belief, the light at the back of the raindrop does not undergo total internal reflection; however, light that emerges from the back of the raindrop does not create a rainbow between the observer and the Sun. The spectra emitted from the back of the raindrop do not have a maximum of intensity, as the other visible rainbows do, and thus the colours blend together and do not form a rainbow.
Each raindrop is shaped like a prism with the narrowest angle at the top. Sunlight enters the raindrop and the "white" light which is really a mixture of the rainbow's colours is bent - or we say refracted. Because of the slightly different wave lengths (red being the longest and violet the shortest) we get the colours separated. Rainbows appear when the sun is behind you and its raining ahead of you. The double rainbow is caused by an internal reflection of the ray of sunlight inside each raindrop.
It's when rain is being reflected by the sun..did you know a rainbow only looks half a circle when really it is a full circle. Therefore, there is no pot of gold at the end because there sin't one!
It has something to do with light. Its like a prism. You can use it to see different colours that appear like a rainbow. Rainbows work in the same way but using water instead of a prism. The water i.e. rain acts like a prism and splits the light spectrum into the seven colours we see as a rainbow. And, if you were to view a rainbow from the air, you would see it was actually a complete circle, not an arch so ther is no end to the rainbow so no one will ever find a pot of gold. It just looks like an arch from the ground.
The pot of gold is NOT nonsense. It comes from Irish mythology and is tied up with leprachauns. All the scientific answers you have been given are fair and correct . But only as far as they go!
Shakespeare (in about 1600) had Hamlet say "There are more things in Heaven and on earth, Horatio, than are thought of in your philosophy". I studied Shakespeare and am happy to go along with the Bard of stratford-on-Avon.
It's a refraction of the light.
That rumour came from the Irish i think lol :P and it is the light refracting off the water particles, which is why it occurs soon after or during the rain.
sun ray's burst through the rain and the spectrum of red blue and green do the rest.
The colors of the rainbow are the "basic spectrum" from which all the light we see is composed. Although these colors merge smoothly, they are sometimes divided into red, orange, yellow, green, blue, indigo and violet (and other names). Just as various musical sounds contain the tones of the basic scale (often combinations of tones, e.g. chords), so any colored light is made up of its "spectral components. "
We only perceive seven colours but if you look closely at a prism, all visible colours are represented
Rod, Jane & Freddie created Rainbow! With the help of George, Bungle & Zippy! And there is a pot of gold!
yOU ARE QUITE RIGHT. the GOLD IS ALWAYS GRABBED BY THE READY AND THE GREEDY AND THEY DON'T HANG A ROUND TO SHARE IT WITH LITTLE HUNGRY ORPHANS, OR THE REALLY VERY NEEDY, tIS A SHAME, BUT IT'S ALWAYS BEEN THE SAME.. bUTNEVER WORRY, BECAUSE WHEN THE SUN ISN'T BUSY REFRACTING LIGHT OFF THE RAIN, THE FAIRIES ARE BUSY BRUSHING COLOURS WITH THEIR JOYFULLNESS AGAIN.
when sun lights touchin' a water in sky you can saw a lots of colours. A long of light makes a diffrent colours. Short lights with little of water making a colour red, yellow but long and not much water makes a colour violet, blue, green
Yes the raindrops do behave like prisms and split up the light, but it is more complicated that that and there is internal reflection inside the raindrop. I have a feeling that the theory was worked out by Peter Debye last century for his PhD thesis (He is normally known as a Physical Chemist and got a Nobel Prize in the 1930's). it isnt simple! People often don't realise that their shadow will always point toward the top of the rainbow even if it isn't visible.
It's basically the refraction of light on droplets of water causing what is 'white' light to break up into its components or spectrum of colours. But I think the angle of incidence plays a part also in the phenomenom which explains why you cannot see it after chasing its tail looking for that elusive pot of gold.
God gave us the rainow as His promise to never flood the earth again ,you would never come to the end of it and certainly not find a pot of gold :)
Not that old question again.
refraction of light through a clear medium - in this case water particles (you get the same effect through glass, diamonds, crystals). Famous Science experiment (if you did Science at school). White light is broken into the 7 primary colors (which is your rainbow): red, orange, yellow, green, blue, indigo and violet (black is not there because it absorbs light and does not reflect.another story for another day).
The end of the rainbow (which is not tangible) is likened to the ever elusive pot of gold. Everyone seeks it, but it's never really found (my version, I don't really know the origins of this).
ok so when you love someone and you look into their eyes, your heart fills up with love so much that it cant contain it all and a little sigh of joy carries it up to the sky where it joins with other sighs of love to make a beautiful rainbow that brightens up your sky.
you cant find the end of it because love is eternal and the pot of gold was used as a trick by an evil guy to try and trick a beautiful young but selfish woman into marrying her so she could make rainbow and find the pot of gold..
Further to mention of the circular rainbow: It is called a 'brockenspectre' and is also referred to as 'the glories'. I saw one after take-off from an airport one rainy morning. As the plane broke through the clouds into blue sky, I glanced down and was astonished. On top of a white cloud just below the plane was this circular rainbow. In the centre was the shadow of the plane.
Apparently the shadow cast upon a cloud combines with droplets of water in the cloud, bending the light to form the rainbow colours. So, if God 'looks down' onto the earth, he will see the circular rainbow. When we look up to the clouds, we see the bow - a sort-of halo above an arched bridge. Very fitting. Thank you, God, for looking down and remembering your promise never to flood the earth again, as in Noah's day. Thank you that we can look up, and that you've bridged the gap between earth and heaven. That's heavenly treasure for us!
