A rainbow occurs when sunlight is refracted, dispersed, and reflected by raindrops. The sun needs to be behind you and the rain in front of you for a rainbow to form, typically when the sun is low in the sky. This creates optimal conditions for the sunlight to be refracted, dispersed into colors, and reflected back towards you to create a rainbow.

What are the appearance and disappearance of rainbow?
A rainbow appears when sunlight is refracted, reflected, and dispersed by water droplets in the air, creating the colors of the spectrum. It disappears as the angle of reflection changes or as the water droplets shift position.
Why does the Suns spectrum contain black lines over an underlying rainbow?
The black lines, known as absorption lines, are created when elements in the Sun's outer layers absorb specific wavelengths of light, leaving gaps in the continuous spectrum. These absorption lines indicate the presence and composition of elements in the Sun's atmosphere. The underlying rainbow spectrum is the continuous emission from the Sun's heated surface.
What is a partial rainbow called?
A partial rainbow is called an arc or a fragment of a rainbow. It occurs when only a portion of the full circle of a rainbow is visible in the sky.

Will there ever be a rainbow twister?
