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.

Rainbows are formed by the dispersion of light & reflection (not total internal reflection) from drops of water. The rainbow color sequence can be analyzed by drawing a ray diagram of the refraction of sunlight inside water drops. Created by Mahesh Shenoy.
Aug 9, 2021 · In the sunny moments after a rain storm, colors fill the sky in an optical illusion involving the refraction and reflection of light. And that's how rainbows are formed.
Oct 19, 2023 · A rainbow is a multicolored arc made by light striking water droplets. The most familiar type rainbow is produced when sunlight strikes raindrops in front of a viewer at a precise angle (42 degrees). Rainbows can also be viewed around fog, sea spray, or waterfalls.

May 30, 2024 · What is a Rainbow? It takes both the sun and rain to make a rainbow! To put it plainly, rainbows are produced by sunlight entering water droplets, bouncing around each individual bead of water, and changing direction (refracting) to reflect off the back of the droplet to return back toward us.
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.
How Rainbows Are Made. A rainbow can form when both sunshine and water droplets are in the sky. Sunlight is white light, which is a mixture of all visible colors. As sunlight passes through the water droplets, it is bent and split into seven colors: red, orange, yellow, green, blue, indigo, and violet. You might be able to see a faint second ...
Mar 15, 2011 · A rainbow is simply a group of circular or nearly circular arcs of color that appear as a huge arch in the heavens. The raindrops act like miniature prisms, refracting or breaking sunlight into...
Sep 23, 2023 · The sequence of the rainbow is made out of seven colors and never changes. The seven colors found inside the spectrum of a rainbow include: red, orange, yellow, green, blue, indigo and violet (ROYGBIV).
Jul 19, 2021 · Creating a rainbow isn't as simple as mixing together sun and water; otherwise, rainbows would follow nearly all rainfall. It's how these two ingredients interact that determines whether or not...
