At their core rainbows form when sunlight interacts with raindrops bending reflecting and separating light into its component colors. This process grounded in optical physics illustrates...

 

Rainbows form when sunlight is refracted internally reflected and refracted again by raindrops splitting white light into colours that emerge at ~40°?42° from the antisolar point.

 

The primary rainbow is caused from one reflection inside the water droplet. The secondary rainbow is caused by a second reflection inside the droplet and this ?re-reflected? light exits the drop at a different angle (50° instead of 42° for the red primary bow).

 

Rainbows are not limited to the dispersion of light by raindrops. The splashing of water at the base of a waterfall caused a mist of water in the air that often results in the formation of rainbows. A backyard water sprinkler is another common source of a rainbow.

 

A rainbow is caused by the refraction dispersion and reflection of sunlight as it passes through raindrops. As light passes through raindrops it bends at different rates causing it to spread out into the colors of the visible spectrum.

 

Rainbows are one of the most admired meteorological phenomena across the globe but how are they formed? Rainbows are formed when light from the sun is scattered by water droplets (e.g. raindrops or fog) through a process called refraction.

 

A rainbow is a multicolored arc made by light striking water droplets. The most familiar type rainbow including this one in southern Chile is produced when sunlight strikes raindrops in front of a viewer at a precise angle.

 

The order of a rainbow is determined by the number of light reflections inside the water droplets that create it: One reflection results in the first-order or primary rainbow; two reflections create the second-order or secondary rainbow.

 

How Our Eyes Perceive Rainbows To be scientifically correct a rainbow is not an object but an optical illusion. What reaches our eyes is visible light which gets processed by the human eye into the vibrant bands of color we associate with a rainbow.
