Several other optical phenomena that appear as colored circles are haloes and coronas (around the light source) and glories (around the point directly opposite the light source). Do not, however, be confused if you see small colored circles of light either around the sun (or moon) or around the point directly opposite the sun (or moon). Looking down from an airplane or a mountain, it is possible to see more of the circle, or even a complete circle. Standing on perfectly flat ground, the largest rainbow we can see is a half circle (when the sun is on the horizon behind us).
#RAINBOW RAINDROPS FULL#
Usually we only see a small section of the full rainbow circle because the rest of it is blocked by the ground in front of us. In a large region of raindrops, the circular symmetry of the drops causes us to see the colors displayed in a circular band in the sky. Our well-rounded team is here to supercharge your brand and bring your creative to life across all channels where your customers spend time. In the case of a rainbow, there are many raindrops in the air, some at the right angle to send red light to our eye, some at the right angle to send blue light to our eye, and some at the right angle to send other colors to our eye. We create marketing people love that earns attention, builds brands and drives results. In fact, you can experience this by looking up close at a drop of water hanging from a flower or blade of grass with the sun behind you. If there really was only one raindrop, you would have to move your head up and down to see the colors change from red to blue. If you look carefully at the blue and red light rays exiting the lower left portion of the water drop in the figure, you might realize that your eye cannot usually see both red and blue from a single drop. The specific angle depends on the purity of the water and the exact wavelength being considered. The angle between the incoming ray of sunlight and the ray that has been refracted twice and reflected once is approximately 40 degrees for blue light and 42 deg for red light. When the reflected light passes back into the air, it refracts (bends) again, which causes the colors to separate even further. The diagram uses a red ray and a blue ray to illustrate how the long-wavelength and short-wavelength light is bent into different angles.Īt the back of the drop, some of the light is reflected (what the diagram does not show is that much of the light passes into the air and continues traveling to the right). Blue light is bent more than red light, with green and yellow in between. Upon entering the drop, the light ray is refracted (or bent) into an angle that depends on wavelength (or color). The diagram illustrates what happens to a single ray of sunlight as it passes through a spherical water drop (actual raindrops are not exactly spherical, but the mechanism is still very similar). Passing white light from a distant source through a raindrop is one way to separate the colors. Sunlight contains the full spectrum of colors that are visible to human eyes, but when nearly equal amounts of all these colors are mixed together, the result is white (or nearly white) light. I added a sentiment and coordinating mat that was also inked to get just the right shade to match.When sunlight encounters a drop of water in the atmosphere it can produce a colorful rainbow because the amount that light rays are bent as they pass in and out of the raindrop depends on the wavelength (or color) of the light. I die cut clouds from glitter cardstock and a sun that I inked up with Mustard seed Distress Ink. Once that was completely dry, I placed my stencil back on top of my panel and added Nuvo glimmer paste on the raindrops (I added a second photo using the flash that picks up the sparkle better but the rest of the photo is much darker). I then stenciled my raindrops, with the same Distress ink colors by masking sections for each color. I started by die cutting my arced strips for my rainbow and inking them with Distress inks. The rainbow-making process begins when sunlight shines on a raindrop.
I created this rainbow card for the theme category in March's Inspirational Card Challenge which is weather. I tend to use bright, vibrant shades but I love soft muted palettes too. I think if someone were to look through my gallery, they'd see that I love color.
