In a primary rainbow, the arc shows red on the outer part and violet on the inner side This rainbow is caused by light being refracted when entering a droplet of water, then reflected inside on the back of the droplet and refracted again when leaving it. What causes a rainbow, why is it curved What are the rainbow colors, how does a double rainbow work, and what's at rainbow's end? 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.
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. A rainbow isn’t really a “thing” and it doesn’t exist in a particular “place.” it is an optical phenomenon that appears when sunlight and atmospheric conditions are just right—and the viewer’s position is just right to see it. A rainbow is an optical illusion —it does not actually exist in a specific spot in the sky The appearance of a rainbow depends on where you're standing and where the sun (or other source of light) is shining. The rainbow is one of the more spectacular light shows observed on earth
The bow part of the word refers to the. 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. Put simply, a rainbow is caused by interaction between sunlight and atmospheric water This most commonly means raindrops, but mist and spray can also cause rainbows.
