A rainbow is an optical phenomenon caused by refraction, internal reflection and dispersion of light in water droplets resulting in a continuous spectrum of light appearing in the sky. The rainbow takes the form of a multicoloured circular arc.

- Red. Red is listed first because it is the first color in the rainbow’s arc. It also has the longest wavelength of any of the colors represented. It is a color packed with vibrancy and strong emotion.
- Orange. The second color of the rainbow, orange is a warm, vibrant color. It is typically a happy color that makes people feel friendly and comfortable.
- Yellow. Yellow is the happiest color in the rainbow. This color of sunshine represents energy and warmth. It is often associated with happiness, clear thinking, and communication.
- Green. Located in the middle of the rainbow, green is the color of life. Here in the West, it is also a color symbolizing wealth, which is why our money is green.

rainbow, series of concentric coloured arcs that may be seen when light from a distant source—most commonly the Sun—falls upon a collection of water drops—as in rain, spray, or fog. The rainbow is observed in the direction opposite to the Sun.

What is a double rainbow?
The term double rainbow is used when both the primary and secondary rainbows are visible. In theory, all rainbows are double rainbows, but since the secondary bow is always fainter than the primary, it may be too weak to spot in practice. Secondary rainbows are caused by a double reflection of sunlight inside the water droplets.

How does a rainbow work?
A rainbow is an optical phenomenon which involves three processes: reflection, dispersion, and refraction. Water droplets can act like little mirrors. When a ray of sunlight strikes one of these tiny spheres of water, most of the light bounces off its rear wall and is reflected back.

What is a primary rainbow?
He explained the primary rainbow, noting that "when sunlight falls on individual drops of moisture, the rays undergo two refractions (upon ingress and egress) and one reflection (at the back of the drop) before transmission into the eye of the observer."

What is the center of a rainbow?
The sun or other source of light is usually behind the person seeing the rainbow. In fact, the center of a primary rainbow is the antisolar point, the imaginary point exactly opposite the sun. Rainbows are the result of the refraction and reflection of light. Both refraction and reflection are phenomena that involve a change in a wave 's direction.
