Have you ever really seen one a double one?

Alrighty then You have forced me to enter information into my computer to understand about double rainbows better known as a secondary rainbow! I feel better thank you!!

as we can see a second rainbow appears over the first rainbow answering the question that was not asked..LOL which rainbow came first. Answer: the bottom one. [] In the first place rainbows are caused by the refraction of light through water droplets, which is true for both. the first one is caused by the light refracting only one time through the water droplet! The second rainbow is then formed by the light being bounced around on the inside of the water droplet causing it to exit at a little different angle, thus producing the second rainbow above the first!

In this information I see that she says, she has seen three rainbows all at once also! Can you imagine how beautiful that would be?

Well You are welcome.. They are very nice last week was the first time I had ever seen a real double one. The one you posted months ago in the other thread was the first one I had ever seen..

I have never seen a double one but once managed to get to the spot where the rainbow touched the ground but failed to find the pot of gold

Wow you guys it is beautiful... gosssssh they really are lovely! All that red. The one we seen last week we could see the end of it all the way to the ground on one end it came down just in front of the hill by the preschool you could see the color in front of the green trees to the ground it was also the first time I saw the rainbows end!

I took this rainbow photo just as the sun was setting, hence the orange clouds.

How high a rainbow arches depends on the height of the sun above the horizon (elevation):
when the sun is near the horizon the rainbow arches highest.

Thats interesting. Thanks Robert!

A couple of months ago I saw a pair of rainbows while I was on my way to work. Both the primary and secondary 'bows were orange.

ME LUFFS RAINBOWS and Waterfalls.. LOL I think Rainbows are spectacular.. The double ones amaze me!

So, it's like a rainbow inside of a mirror house?

edulofter · « **Reply #19 on:** 26/05/2019 02:01:16 »

On occasion, you may have seen two rainbows at once. The lower rainbow is the primary rainbow and the higher, fainter, colored arc is the secondary rainbow. The color sequence of the secondary rainbow is opposite to the primary; red is on the inside of the arc and violet on the outside.

When sunlight passes through a triangular glass prism, it separates into the colors of the rainbow. This separation happens because different colors bend, or refract, by different amounts. The shortest (blue and violet) wavelengths refract the most; red light refracts the least.

The separation of colors is referred to as dispersion. Not only prisms but also water drops and ice crystals can cause dispersion. To form a rainbow you need large drops of water, the sun at your back and at the correct angle.

Raindrops act as prisms, bending and reflecting the sunlight that falls on them, just like a crystal hung in a sunny window.

As light enters water, the path it takes changes. How much the direction changes is a function of the color of the light.
You probably noticed that a smooth water surface can act like a mirror and reflect light. If the light beam entering the raindrop reaches the back of the drop at a certain angle, it undergoes a reflection and heads back toward the sun. As the light exits the raindrop and re-enters the air, its path bends an amount that again depends on the color. This bending of the light as it enters and leaves the drop disperses the light of the sun into its spectrum of colors that form the rainbow.
Sometimes the light reflects twice off the back of the raindrop
