What Can We Learn From A Rainbow?

What is a rainbow? rainbow

Rainbows can be observed whenever there are water drops in the air and sunlight shining from behind at a low altitude angle. Rainbows can also be seen near waterfalls or fountains. A rainbow is caused by light refracting through water droplets (rain/water) in the atmosphere, resulting in a spectrum of light.  The rainbow appears when you are between the droplets and the sun is behind you. The light from the sun is refracted as it enters the surface of the raindrop, refracts off the back of the drop and again refracts as it leaves the drop, resulting in a multicolored arc.

What Makes the Colors?

The amount of light refracted affects the color. Blue has a shorter wavelength and is refracted at a greater angle, thus it is seen as the smallest arc on the inside of the rainbow and red, due to a longer wavelength, is seen as the most dominant color and a wider arc, on the outside.

What Causes a Double Rainbow?

When there is a double reflection of sunlight inside the raindrop, a secondary rainbow may be seen, but the colors will be inverted compared to the first, with blue on the outside and red on the inside.

What About Rainbows in Literature? I found several beautiful references to rainbows:

And the bow shall be in the clouds…And God said to Noah, This is the token of the covenant, which I have established between me and all flesh that is upon the earth. Genesis 9:17 (KJV)

 

Through gloom and shadow look we

On beyond the years!

The soul would have no rainbows

If the eyes had no tears. John Vance Cheney, in “Tears” in the Century - 1892

 

We, of many cultures, languages and races are become one nation. We are the Rainbow People of God.Desmond Tutu, in speech before the National Assembly of South Africa, - 1994

 What is the rainbow? Sunlight turned back to our eye, through drops of falling rain. What sign could be more simple? And yet what sign could be more perfect? Charles Kingsley, in “God’s Covenants” from the Works of Charles Kingsley, - 1885

God put the rainbow in the clouds, not just in the skyIt is wise to realize we already have rainbows in our clouds, or we wouldn't be here. …in the worst of time, there is the possibility of seeing hope. We can say "I can be a rainbow in the cloud for someone yet to be." That may be our calling. Maya Angelou – Harrisburg Forum – 2001

 

Author’s Corner:  Do we write to create a rainbow for our readers? Do your characters, themes and plots engage and edify the reader? When someone buys your book, they’ve placed their confidence in your ability to entertain or enlighten them in some way. You have an opportunity. Make your words count for something worthwhile.

Everyone Else: You have a choice. When you encounter others who project anger, sadness, or a mean spirit, don’t withhold the light and reflect only the blue aura of yourself. Let the sun shine through your spirit. Reflect the widest angle of red in your rainbow and be a friend to those you meet!

    Most interesting post. I often think of God telling us a rainbow is His promise to us that He'll never flood the earth again when I see one. I've only seen one double rainbow and grabbed the camera to take pics.

      Of course that's what the bible tells us the rainbow is all about. Nice to be reminded after a rainy stormy day.
