Rainbows and the mechanics of them have been studied since ancient times. Greek philosophers had some understanding of the role of refraction, scientists in the 13th century produced theories on rainbow formation, and in the 17th century, Rene Descartes sketched out the conditions required to observe a rainbow (Douma).
There are two key aspects that affect a rainbow, and these include the altitude of the sun and the size of the raindrops. The colors of the rainbow are because of two basic facts:
• Sunlight is made up of the whole range of colors that the eye can detect. The range of sunlight colors, when combined, looks white to the eye. This property of sunlight was first demonstrated by Sir Isaac Newton in 1666.
• Light of different colors is refracted by different amounts when it passes from one medium (air, for example) into another (water or glass, for example) (University Corporation for Atmospheric Research).
Determining whether or not the wavelengths will go through the raindrops or reflect depends on the angle that the light falls on the backside of the raindrop. Each rain droplet has a function in the formation of the rainbow. Sunlight enters the rain droplet at a specific angle and the rain droplet separates the white light into many different colors. This angle is a fixed measurement between your eye and the sun. What color that is refracted is dependent on the critical angle, the angle the sunlight strikes the back of the rain droplet (Mahlen).

Light is a form of energy that behaves in some ways like waves. Light waves have a range of wavelengths. A wavelength is the distance between any point on one wave and the corresponding point on the next wave. Different wavelengths of light appear to us as different colors. Light that contains all wavelengths in the same proportions as sunlight appears white. See LIGHT.

The rain shadow effect starts on the westward side of a mountain, and the air on the mountain is forced to rise which makes the air cooler. As the air cools it loses the ability to hold water, the precipitation occurs on the westward side. As the air travels to the other side, the leeward side it no longer contains moisture. Lake effect and rainshadow are similar to each other because of the fact that they both have a huge impact on precipitation and
Which of the following can be attributed to refraction of light in theA.The green flash, which is a light green color on the upper rim of the Sun as it is setting
The origin and history of this myth is mostly unknown, no one really knows how this story came to be and when, but people do know that this tale originated from the Ojibwe Nation and was retold by S. E. Schlosser. After that other tribes started to adopt the myth of how the rainbow was made, including my tribe the Tohono O’odham Nation. People also know that this tale is very old that’s one of the reasons why no one knows when it was created because it was so long ago.
“Those colors are from sulfur and iron oxide mainly,” Norval said, revealing more of his encyclopedic knowledge of Gnaritus’ geology. “There are many colorful rainbows on Gnaritus not only in the sky but also on the land!”
Pigments-pigments change the colour from the natural colour to make it more pigmented which is making the colour stronger and
A rainbow is caused by the reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. . It takes the form of a multicolored arc; Rainbows caused by sunlight always appear in the side of sky directly opposite the sun. A primary rainbow the arc shows red on the outer part and violet on the inner part.
Like butterflies and hummingbirds that acquire their colour when light hits their bodies, opals gain their ‘play of colour’ when a light ray encounters small obstacles or slits. When the light wave bends as it passes around the edge or through the small openings, the ray breaks apart and scatters the wave into visible rainbow hues. This phenomenon is known as diffraction. To understand how this happens, you need to learn the structure of opals.
How are the colors of the Northern Lights created? "The atmosphere contains mostly nitrogen and oxygen, which the characteristics colors of their respective line spectra." [webexhibits.org] The Northern Lights, also known as the Aurora Borealis, has many elements in the surface of the earth. There's atomic oxygen, nitrogen, mixed with hydrogen. "Only one of these elements are responsible for the two main colors which are green and red." [webexhibits.org] You would think that the Aurora was just lights appearing in the sky but they're actually distractions between electrically charged particles from the sun that comes into the earth's atmosphere. [northernlightscentre.ca] The most common colors are green, yellow, and red. Nitrogen causes most of the blue, purple, and red parts, the bright cool colors. Atomic oxygen causes most of the orange and yellow parts, the warm colors. Northern Lights are like curtains in the sky
Refraction is light that is deflected in passing through the something “between one medium and another or through a medium of varying density” (Google Dictionary) Transparent is anything that can be seen-through and allows light to pass totally through. Translucent is an object that allows some light to transmit through but absorbs some of it as well. Opaque is an object that does not allow light to transmit through it.

The sky is blue because molecules in the air spread blue light from the sun more than they spread red light. At sunset, the colors turn orange and red because the blue light has spread out more, and we can no longer see the line of blue. The Tyndall effect was discovered by a man named, John Tyndall. He found out that when small particles in the air are suspended the shorter blue wavelengths are more scattered. Water vapor in the air accounts for why we see the blue sky too. The more of the dust and drops of water there are in the air, the more blue the sky seems. When the air is more clear that is when we see the oranges and red that are shown at sunsets. The color of the sky in all comes from how the electromagnetic field is
When light passes from the air into a different medium, like water, it is refracted. You can see this by putting a pencil in a cup of water. The pencil appears to bend, but it isn’t actually bent. Again, this is because of refraction. Putting a pencil in a cup of sugar water would also cause refraction, but the amount of light refracted would be different.
If white light falls on one of these molecules, some wavelengths are absorbed by these delocalised electrons. The colour you see is the result of the non-absorbed wavelengths. The groups which contribute to the delocalisation (and so to the absorption of light) are known as a chromophore.
The speed of the wavelength of white light before it hits the raindrop determines the color a raindrop will emit. If the wavelength of white light travels at a slow speed, then the wavelength of light will bend more when it enters the raindrop.
