At the edge however, these colored discs don't overlap so display their individual colors producing the rainbow arc.Ī "double rainbow" is where a second, much fainter arc can be seen outside of the primary arc. This is due to the fact that the millions of droplets needed to make a rainbow are spherical and overlap to create white light. The sky within a primary rainbow is brighter than the sky outside of the arc. Most rainbows we see will be a "primary rainbow" whereby the color red can be seen on the outer edge through to violet on the inner edge. All of which are present in a rainbow in the order red, orange, yellow, green, blue, indigo and violet (the acronym or name ROY G BIV is a good way to remember these colors and their order). Sir Isaac Newton identified the 7 colors of the visible spectrum that together make up white light. Rainbows can be seen not just in rain but also mist, spray, fog, and dew, whenever there are water drops in the air and light shining from behind at the right angle. If someone appears to be standing under a rainbow you can see, they will see a different rainbow at the same angle but further away. ![]() No two people see the same rainbow, in fact even our individual eyes see slightly different rainbows. ![]() However, due to most people viewing a rainbow on the ground we only see a semi-circle or arc of the rainbow.Ī rainbow is not situated at a specified distance, instead it will always be visible to a person at the precise angle freshwater droplets reflect the light which is 42 degrees in the opposite direction of the sun.Ī rainbow is not an object, it cannot be approached or physically touched. Rainbows are created by both reflection and refraction (bending) of light in water droplets in the atmosphere, which results in a spectrum of light appearing.Ī rainbow is in fact a full circle of light. A rainbow is a multi-colored arc that forms in the sky.
