How Do Rainbows Form?
A rainbow is an optical phenomenon which involves three processes: reflection, dispersion, and refraction.
Is There a Pot of Gold at the End of the Rainbow?
According to an Irish legend, a pot of gold can be found at a rainbow’s end.
Need Help Choosing?
We’ll help you build your dream Rainbow that your family will enjoy for years to come.
What Causes a Rainbow?
If you had no idea at all about what a rainbow is or what causes it, you might actually believe some of the legends that different ancient cultures have created to explain it.Rainbows are among the most beautiful of nature’s displays.
What happens in the water droplets?
The sunlight shines on a water droplet.As the light passes into the droplet, the light bends, or refracts, a little, because light travels slower in water than in air (because water is denser).Then the light bounces off the back of the water droplet and goes back the way it came, bending again as it speeds up when it exits the water droplet.
What Is a Double Rainbow?
Double rainbow in Finland.
What makes a double rainbow?
A secondary rainbow appears if the sunlight is reflected twice inside the water droplets.Secondary rainbows are fainter, and the order of the color is reversed, with red on the bottom.Credit: Leonardo Weiss via Wikimedia Commons.

When can you see a rainbow?
A rainbow requires water droplets to be floating in the air.That’s why we see them right after it rains.The Sun must be behind you and the clouds cleared away from the Sun for the rainbow to appear.
Why is a rainbow a bow—or arc?
A full rainbow is actually a complete circle, but from the ground we see only part of it.From an airplane, in the right conditions, one can see an entire circular rainbow.
Why Is a Rainbow Curved?
Technically, a rainbow is the upper half of a circle of light, which centers on the antisolar point, the point directly opposite the Sun, as seen from your perspective.The lower half of the circle, however, is usually not visible since the water droplets hit the ground before it can form.You may be able to see a circular rainbow if you have a high vantage point and the terrain sharply drops off in the direction of the rainbow, allowing the rain to fall down farther and reflect the sunlight from a lower angle.It is also possible to see a circular rainbow from an airplane.
Why Is the Area Below the Rainbow Brighter?
While most of the sunlight is concentrated at an angle of 40-42°, some of it is also reflected in the range of 0-39°.Crucially, the angle also determines the extent to which the sunlight is dispersed and refracted.For example, a ray of light that is reflected at 0°—right back where it came from—is not dispersed or refracted at all.
Why the colors?
Sunlight is made up of many wavelengths—or colors—of light.Some of those wavelengths get bent more than others when the light enters the water droplet.Violet (the shortest wavelength of visible light) bends the most, red (the longest wavelength of visible light) bends the least.So when the light exits the water droplet, it is separated into all its wavelengths.The light reflecting back to you, the observer with the Sunlight coming from behind you, from the water droplets will appear separated into all the colors of the rainbow! Violet will be on the bottom and red on the top.
