Why can’t we reach the end of a rainbow? ›

A rainbow isn't a fixed object that hangs in the sky. It's an illusion formed between the sunshine, the rain and your eyes. Light bounces out of the raindrops at an angle of 40° for red light, and 42° for blue. And that's true wherever you stand, so as you move, the rainbow moves too and you can never catch it.

It's an optical phenomenon that depends on the viewer's position relative to the sun and the rain droplets in the sky. As you move towards it, it appears to move away from you, hence you can't reach it.

As a rainbow is simply a form of optical illusion, as you move around where light is reflected by the rain the view also changes. No matter how, or where, you move the rainbow will always move further away making that pot of gold forever unattainable.

Because rainbows are made in the sky, they don't touch the ground. So if you're on the ground, however far you walk, the end of the rainbow will always look as if it were on the edge of the horizon. But what people don't realise is that rainbows are actually complete circles, and obviously a circle has no end.

Rainbow is formed just because of dispersion of white light due to raindrops. Technically different colours are light waves of different wavelengths. Since we can not touch light, so we can not even touch a rainbow.

No. A rainbow is a visual phenomenon. Anyway, sometimes you can see it is in fact a circular rather than a semi-circular image.

You have to be at the right angle to see one, and so you couldn't actually stand underneath one as (I think) if you moved forward an inch the rainbow would move accordingly.

Patrick's Day is right around the corner, and with it comes tales of mischievous leprechauns and the pots of gold that they guard at the end of rainbows. You may already know that there is no “end” of a rainbow — science tells us that their arch shape is simply an illusion.

There are infinite colors in a rainbow, but we only see the seven colors (VIBGYOR). It comes down to the way our eyes function. Even though a rainbow has a lot of colors, the cells in our eyes only respond to three: Red, Green, and Blue.

Does a rainbow ever hit the ground? ›

Rainbows never actually touch the ground! They look like they do due to a prism-ing effect but if you go high enough, in a plane or on a mountaintop, and look down on a rainbow; it will be completely circular!

Nah, the rainbow is an optical effect of light going through rainy air and into your eye. If you move, then light is hitting your eye at a different angle through a different bit of rain - depending on the conditions, either the rainbow will move or it'll disappear from your perspective.

What about triple rainbows? “First, yes, they exist”, clarifies Hwong. “Yet, a true third-order rainbow should not be confused with the much more common phenomena of supernumerary bows and reflection rainbows.” Third-order or tertiary rainbows originate from three reflections inside the droplet.

You can't “chase down the end of a rainbow,” because a rainbow has no fixed ends. It's like a reflection; it depends on where you are: You will always see the end of a rainbow as being far away. If you move, the perceived end of the rainbow moves with you.

The truth is, a rainbow has no physical existence and therefore has no distance or size. It is merely an optical illusion created by the interaction of sunlight with water droplets in the atmosphere.

If you stare at something for a while without moving your eyes around to refresh the image, the retina degrades the image and it becomes blurry. That's true of anything you look at, and as rainbows are slightly less distinct, it's more difficult for the eye to get a fix on it, and so they probably degrade more easily.

On a bright, sunny day, the head of your shadow marks the antisolar point. Every rainbow is a perfectly circular ring centered around this very spot. Yet if you're standing at ground level, you won't be able to see the circle's lower half.
