Rainbows
Rainbows are an optical phenomenon that can be seen in the sky when the sun reflects off the water droplets from rain or the mist of a waterfall. This causes a spectrum of light known as a rainbow. Questions about rainbows can be directed here.

What is the opposite of a rainbow?
A moonbow, I think. It is a lunar rainbow, meaning the light comes from the moon instead of the sun. When looked upon by the human eye they appear to be white.
What has light to do with a ranbow?
A rainbow is created when sunlight is refracted, or bent, and scattered in raindrops, splitting the light into its different colors. Each color in the rainbow corresponds to a different wavelength of light, creating the beautiful spectrum we see.
A rainbow appears when sunlight is refracted and reflected by raindrops in the sky, creating a spectrum of colors. Rainbows can occur when there is a combination of sunlight and rain, usually during or after a rain shower.
Rainbow roses are real roses that have dyes injected into the steams to give the flowering part of the rose a rainbow effect. Rainbow roses can be purchased online and delivered from web sites such as JustFlowers.com, among others that you can locate by using google.
No, a rainbow is not made of matter. It is an optical and meteorological phenomenon that occurs when sunlight is refracted, reflected, and dispersed in water droplets in the Earth's atmosphere, creating a spectrum of colors.
What is a rainbow and what causes it?
internal reflection of sunlight inside raindrops and/or mist droplets.
Answer:
Light from the sun appears to be colourless but it is really made up of all seven visible colours (red, orange, yellow, green, blue, indigo and violet). When the "white" sunlight enters a raindrop it breaks up into the various colours (due to a process called refraction) and bounces back out of the drop towards your eyes when it reflects off the rear surface of the raindrop.
For this to occur the sun has to be shining and you have to be between where the sun is in the sky and the rain or mist droplets are located. You can make your own rainbow with a garden hose set to mist on a sunny day or by using a prism,
What property of light causes rainbows to form?
White light is the combination of the colors that form a rainbow. Those colors are Red, Orange, Yellow, Green, Blue, Indigo, and Violet (ROYGBIV). A rainbows form because white light is shone through water droplets which acts as a prism slowing down the different wavelengths of these different color lights causing them to split up into their individual components again.
What is the importance of the rainbow?
The rainbow offers a representation of the visible spectrum of light for human eyes, this is a wavelength of 400nm. The mnemonic device "Roy G. Biv" is easily remembered to dictate the order of the colors: red, orange, yellow, green, blue, indigo and violet. Any other visible colors are a derivation of these.
They are formed when it is raining outside and there is also sunlight.
White light from the sun does not have 1 specific wavelength. It's like asking what is the average height of 5 brothers. All colours have different wavelengths.
When white light is refracted from a water particle. Every colour has a different wavelength. Blue is the shortest and red is the longest. Therefore blue takes more time to cross the water particle then the red wavelength. In fact, all wavelengths from the sun light cross the water particle at different times. This creates a diffraction pattern that is always the same… a rainbow.
it is when it is cloudy and warm when it starts raining you can see it but the sun has to be out shining behing the rainbow a rainbow is like rain in front of you a rainbow is made by rain and sunshine and clouds
How does refraction cause rainbows?
The actual mechanism is a little difficult to explain without a drawing. But, simply stated it's because white light contains all colors. And, when light goes from one medium into another (in this case from air into water droplets) the light is bent, and each color is bent a different amount, thus separating them. Then the beams of color are bent a second time as they go from the water back into the air. This fans out the colors into the rainbow you see. This bending of light is called refraction.
As I said, without a drawing it's difficult to explain why the colors bend different amounts as they pass through the water/air boundry, but it's because different colors are different frequencies or wavelengths of light, and different wavelengths are bent different amounts.
How does rainbows relate to physic?
Rainbows are related to physics through the lens effect of water drops. Water in the atmosphere acts as a lens and bends sunlight passing through the drops producing the colors of the rainbow. Newton demonstrated this lens effect, demonstrating that "white light" was composed of colored light.
A rainbow maker is a device that uses sunlight to create rainbows indoors by dispersing light through prisms or other reflective surfaces. It is often used as a decorative or relaxing piece of art in homes or offices.
What is the name of the rainbow?
A Moonbow
lmao that kinda sounds stupid sorry but i saw one and yea i mostly called it a
Black Rainbow cuz it had grey but the grey rainbow sounded stupid so i just called it the
BLACK RAINBOW Enjoy =]
What does the term ''refraction'' mean in terms of rainbows?
Refraction in terms of rainbows refers to the bending of light as it passes through water droplets in the atmosphere, creating the vivid spectrum of colors that form a rainbow. This bending occurs because light changes speed as it moves from air to water, causing different colors of light to separate and become visible.
How are reflection and refraction both involved in rainbows?
Reflection occurs when light waves bounce off the inside surface of a raindrop, then refract when they exit the raindrop at a different angle. This refraction causes the different wavelengths of light to separate and create the colors of the rainbow.
What is refraction mean in the terms of rainbows?
Refraction in the context of rainbows is when sunlight enters a raindrop, bends (changes direction), reflects off the inside surface of the raindrop, and then exits the drop. This bending of light causes the sunlight to separate into its different colors, producing the rainbow.
A rainbow is a natural optical phenomenon that occurs when sunlight is refracted, reflected, and dispersed in water droplets in the Earth's atmosphere. It is not made of matter in the traditional sense, but rather is a beautiful display of light and color.
-We see rainbows when the sun is behind us and falling rain is in front of us.
-When sunlight strikes a falling drop of water, it is refracted, changed indirection, by the surface of the water.
The light continues shining into the drop of water and is reflected from the back of the drop to the front. When the beam hits the front of the drop of water, it is refracted again and it emerges from the drop as the colour spectrum that we see in a rainbow.
-The water drop acts like a prism to separate the light into its different wave lengths.
DOUBLE RAINBOW-If the beam is reflected twice inside the water drop, it will cause a secondary rainbow to appear when the light leaves the water drop. The colours of the secondary
rainbow are reversed in order with violet
on the top and red at the bottom.
Rainbows are neither liquid nor gas. They are optical phenomena caused by the reflection, refraction, and dispersion of light in water droplets in the atmosphere, creating a spectrum of colors in the sky.
Because its an optical illusion. It looks like it falls on the horizion, but the more you travel towards it, it remains the same distance away. The rainbow that you actually see is only part of a circle of the rainbow in the sky. We normally only see a segment or an arc from horizion to horizion. On certain conditions when the upper level atmosphere is just right, an entire circle of the rainbow can be seen and on rare occasions, even multiple ones. == ==
Is a rainbow always the same size for the height and distance between the feet of the rainbow?
No, the size of a rainbow can vary depending on the height of the sun, the size of the raindrops, and the observer's position. The height and distance between the feet of a rainbow can change depending on these factors.
You can see a rainbow when sunlight is refracted, reflected, and dispersed through water droplets in the air, such as after a rain shower or near a waterfall. The most common time to see a rainbow is when the sun is low in the sky, at around a 42-degree angle from your eyes.
What does a rainbow feel like?
A rainbow is a natural phenomenon and cannot be physically touched or felt. It is formed by the refraction and dispersion of sunlight through water droplets in the atmosphere, creating a beautiful display of colors in the sky.
