Have you ever ever seemed up on the sky after a rainstorm and seen a ravishing arc of colours? That is what we name a rainbow. Rainbows are shaped when daylight passes by way of water droplets within the air, they usually all the time seem in the identical order. On this article, we are going to discover the seven colours of the rainbow and study in regards to the science behind this fascinating pure phenomenon.
The colours of the rainbow are crimson, orange, yellow, inexperienced, blue, indigo, and violet. These colours are sometimes remembered utilizing the acronym ROY G. BIV. Every coloration represents a unique wavelength of sunshine, with crimson having the longest wavelength and violet having the shortest. When daylight passes by way of water droplets, it’s refracted, or bent, and the totally different wavelengths of sunshine are separated. This separation is what creates the rainbow’s colours.
Now that we all know what causes a rainbow, let’s take a better have a look at every of the seven colours.

7 colours in a rainbow
The seven colours of the rainbow are crimson, orange, yellow, inexperienced, blue, indigo, and violet. These colours are sometimes remembered utilizing the acronym ROY G. BIV, which stands for the primary letter of every coloration.
Every coloration within the rainbow represents a unique wavelength of sunshine. Crimson has the longest wavelength and violet has the shortest wavelength. When daylight passes by way of water droplets within the air, it’s refracted, or bent, and the totally different wavelengths of sunshine are separated. This separation is what creates the rainbow’s colours.
The colours of the rainbow all the time seem in the identical order. Crimson is all the time on the surface of the rainbow, and violet is all the time on the within. It is because crimson mild has the longest wavelength and is refracted the least, whereas violet mild has the shortest wavelength and is refracted essentially the most.
Rainbows are sometimes seen after rainstorms, however they may also be seen round waterfalls or different our bodies of water the place water droplets are suspended within the air. Rainbows may also be created artificially utilizing a prism or a water hose.
The seven colours of the rainbow are a ravishing and interesting sight. They’re a reminder of the ability of sunshine and the fantastic thing about nature.
ROY G. BIV acronym
ROY G. BIV is a mnemonic acronym used to recollect the colours of the rainbow so as. It stands for the primary letter of every coloration: Crimson, Orange, Yellow, Inexperienced, Blue, Indigo, and Violet.
ROY G. BIV is a useful instrument for studying and remembering the colours of the rainbow, particularly for kids. It may also be used to show youngsters in regards to the totally different wavelengths of sunshine. For instance, you might clarify that crimson mild has the longest wavelength and violet mild has the shortest wavelength.
ROY G. BIV may also be used to create enjoyable actions for kids. For instance, you might make a ROY G. BIV cell by hanging totally different coloured objects from a string.

Daylight refracted by water droplets
When daylight passes by way of water droplets within the air, it’s refracted, or bent. This bending of sunshine is what causes rainbows to type.
As daylight enters a water droplet, it’s slowed down. This causes the sunshine waves to bend, or refract. The quantity that the sunshine waves are refracted is dependent upon their wavelength. Crimson mild waves are refracted the least, whereas violet mild waves are refracted essentially the most.
After the sunshine waves are refracted, they’re mirrored off the again of the water droplet. This reflection causes the sunshine waves to bend once more, or refract, as they exit the water droplet.
When the refracted mild waves exit the water droplet, they’re separated by wavelength. This separation is what creates the rainbow’s colours. Crimson mild waves are on the surface of the rainbow, and violet mild waves are on the within.
The angle of the solar and the place of the observer are additionally essential elements within the formation of rainbows. For a rainbow to be seen, the solar should be behind the observer and the water droplets should be in entrance of the observer.
Colours separated bychromatic dispersion
Asamatic dispersion is the phenomenon that causes mild waves of various colours to be refracted, or bent, at totally different angles. This separation of colours is what creates the rainbow’s distinct bands of coloration.
-

-
The opposite colours of the rainbow fall in between crimson and violet when it comes to how a lot they’re refracted.
This is the reason the rainbow seems with a easy gradient of colours.
-
The angle of the solar and the place of the observer are additionally elements that have an effect on how the colours of the rainbow are separated.
This is the reason the rainbow seems in numerous styles and sizes.
The colours of the rainbow are a ravishing and interesting sight. They’re a reminder of the ability of sunshine and the fantastic thing about nature.
Seems reverse the solar
Rainbows are all the time seen reverse the solar. It is because the sunshine from the solar should cross by way of water droplets in an effort to create a rainbow. When the daylight hits the water droplets, it’s refracted, or bent. The totally different colours of sunshine are refracted at totally different angles, and this separation of colours is what creates the rainbow.
-
The solar should be behind the observer in an effort to see a rainbow.
It is because the sunshine from the solar should cross by way of the water droplets in entrance of the observer in an effort to create a rainbow.
-
The rainbow might be highest within the sky when the solar is lowest within the sky.

-
The rainbow might be wider when the water droplets are bigger.
It is because the bigger water droplets refract the sunshine greater than the smaller water droplets.
-
Rainbows can typically be seen at evening.
That is known as a moonbow. Moonbows are a lot fainter than rainbows as a result of the moonlight is far weaker than the daylight.
Rainbows are a ravishing and interesting sight. They’re a reminder of the ability of sunshine and the fantastic thing about nature.
Image of hope and new beginnings
Rainbows have lengthy been related to hope and new beginnings. It is because they’re usually seen after storms, which will be symbolic of inauspicious occasions. When a rainbow seems after a storm, it may be an indication that the storm is over and that higher days are forward.
