Rainbows are formed through refraction. The refraction happens through the rain drops, causing the light (which is made up of a spectrum of colours) to split and causes a rainbow.

Richard Of York Gave Battle In Vain -> Red, Orange, Yellow, Green, Blue, Indigo and Violet. This is the order in which it refracts.

Why would you never see a rainbow in the southern sky if you were in the northern hemisphere?

The diffraction of light from thesunto form arainbowrelies on the sun being behind the observer.In general terms when you are in the northern hemisphere the sun is always south of you, even if its by a tiny amount, so the rainbow will always be north of you. This means you will not see a rainbow (caused by the sun) in the southern sky.To be absolutely accurate however due to the axial tilt of the earth there is a zone near theequatorwhere the sun is in fact slightly north of you for about half the year and you are still in the northern hemisphere (which comes from the position of the equator not the sun). In this zone it is possible so see a rainbow in the southern sky.


Why is the sun shining on the raindrops important in making a rainbow?

becasue the rain bends the light from the sun thus casueing a rainbow The raindrops act as a prism and refract the light from the sun, causing it to break up into the colors of the spectrum. This happens because the color we see depends on the angle of refraction. Passing through a prism or a raindrop, different parts of the light are bent by different amounts, and so they get separated.


What is a rainbow?

It is a rule that violet light bend that most and red color bend least way. Most of the light passes through the rain drop. Because of bending of colors in different ways and on different angle each color that emerges from raindrop produce a spectrum of colors. As only single color from each drop reaches to observer, so there are number of raindrops from which each rain drop reflect the light back to an observer at slightly different angle, as to produce different primary colors of rainbow. Secondary rainbow appears above the primary rainbow. When two colors reflection occur inside a raindrop at such angle that it results into secondary rainbow. When weaker light that start emerging to produce a dimmer rainbow effect. Refraction happens as light enters and leaves a prism. Red light is refracted the least and violet light is refracted the most. This causes the different colours in the light to spread out to form a spectrum. Separating the colours like this is called dispersion. We say that the light has been dispersed.


What are the colors that form the other rainbow colors?

The colors of the rainbow are RED ORANGE YELLOW GREEN BLUE INDIGO VIOLET.Red, Yellow & blue are primary so no colors make up them.Green=Yellow+BlueViolet=Blue+RedIndigo=Violet+Blue


When and where do you see a rainbow?

You can see a rainbow when sunlight is refracted, reflected and dispersed in raindrops, typically after a rain shower. Rainbows are usually seen when the sun is low in the sky, and the observer's back is facing the sun.

What angle do you have to be at to see a rainbow?

One doesn't have to be at any specific angle to see a rainbow. What is Dependent on seeing the rainbow is the location of the rain, and sun relative to you. The sun is always behind a rainbow when seen. So you would be in front of the rainbow, rain, and the sun. Also, No two people see the same rainbow unless a picture or video was taken of the rainbow.


Are rainbows always in the east?

Rainbows are not always in the east; their position depends on the angle of the sun and the observer's location on Earth. Rainbows are generally seen in the direction opposite the sun, so if the sun is in the west, the rainbow will be in the east.


Why cannot you see a rainbow at noon?

Rainbows usually form when sunlight is refracted and reflected off water droplets in the atmosphere, creating the spectrum of colors. At noon, the sun is directly overhead, so the angle at which sunlight hits the water droplets is not conducive for rainbow formation. The sunlight needs to hit the droplets at a specific angle to create a rainbow, which is why they are typically observed early in the morning or late in the afternoon.


Can you see a rainbow if you stand with your back towards the sun?

For a rainbow you need rain and sunshine at the same time. So this is possible on a partly cloudy day.


How come when you get close to rainbow it seem as if it further back?

The rainbow is an optical effect caused by the angle at which the sunlight hits the water droplets in the air. As you move, this angle remains the same, so the rainbow appears to move.


Why are rainbows so rare at noon?

Rainbows are more common in the morning or evening because the angle of the sun is lower, creating a greater chance for the sunlight to be refracted and dispersed by raindrops in the atmosphere. At noon, the sun is higher in the sky, which tends to minimize the conditions needed for a rainbow to form.


Do rainbows appear in the same place on different days?

If you are in the same place, the rainbow will always appear in the same place because it all has to do with the angle you are at in relation to the sun (42 degrees - see the related link). So if you are always in the same spot (e.g. at your desk at work), the sun will be coming from the same same angle, creating the rainbow in the same spot. My understanding of what I've read, you'll only see a rainbow in a certain place in the sky from the same spot at a certain time of the year because the sun moves depending on the season. Also, it is not only the angle of the sun but also the height of it that has to be the same.


Why the rainbow is semi circle in shape?

Actually it is circular but usually the sun needs to be quite low in the sky for the angle of the sunbeams hitting the raindrops to be suitable to create a rainbow visible from the ground. But, when that happens, a part of the rainbow is cut-off by the horizon and so it appears semicircular. Full circles are rare but have been seen/photographed.


When does Iris' symbol appear?

After it rains, and the sun comes out. Iris' symbol is a rainbow so after the rain comes a rainbow.


Why do rainbows disappear?

Rainbows disappear when the water droplets in the air evaporate or move out of the sunlight's path, causing the sunlight to no longer be refracted and reflected to create the rainbow. Rainbows can also disappear when the angle between the observer, the sun, and the raindrops changes.


Why do you see a rainbow only after it rain?

A rainbow is created when sunlight is refracted and reflected off raindrops in the air. Raindrops act like tiny prisms, separating sunlight into its different colors. So, a rainbow can only be seen when there are raindrops in the air and sunlight at a specific angle.


Which chemicals make a rainbow?

A rainbow is formed as a full visible spectrum, where there is a completely graded system of particle size, or of viewing angle. The common airborne rainbow is composed of water droplets, which, depending on the observers angle, span the full visible spectrum. You may also see a rainbow of colour on the surface of a CD, where the grooves form a diffraction grating. Another different rainbow is formed when a thin film of one liquid is spread out over another fluid - without mixing. This is your common gasoline rainbow on a puddle. Back in the day when film transparencies were commonly mounted in glass covers, then 'Newton's Rings' of a rainbow may show as the angle between the media change. And of course, a rainbow is formed when white light passes through a prism - the chandelier and the diamond ring are examples. So, the phenomenon is one of angle, not particularly of chemical nature.
