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.

Why did God create rainbows?

User Avatar

Asked by Wiki User

The rainbow colors visible when sunlight behind you bounces off water droplets such as rain ahead are consequential to laws of physics and the event of light refracting twice and bouncing once around the inside of the spherical droplet. While they probably existed since the beginning of creation, in Genesis 9:12-17 rainbows became token of a covenant from God that the Earth would never again be flooded as it was in the days of Noah.

Why rainbows are colorful?

Because the degree to which light refracts depends upon its wavelength. Red with the longer wavelengths refracts the least and blue the most with the shorter wavelength, so you end up with a rainbow effect, with the white light split into a spectrum.

How does rainbows appear in the sky?

Sunlight being refracted by rain.

When you see a rainbow, stand with your back to the Sun. The centre of the rainbow is in a direct line from the Sun, through you to the centre of the bow.

From that line the coloured bow is angled at 42 o (degrees).

There are seven colours; they are red, orange, yellow, green, blue, violet and indigo. The red is always on the outside of the bow and the indigo on the inside of the bow. This is because the wavelength of red light is longer, so it is seen on the longer(outside) edge. Conversely, the wavelength of indigo light is shorter, so it is seen on the shorter(inside) of the bow.

Because of 'light bending' the outside of the red edge is darker. Conversely the inside of the indigo edge is lighter,

If the rainbow is very bright, you will see a reflected bow outside the main rainbow. In the reflected bow the colours and light bending are reversed. On the very rare ocassions you may see a triple bow, outside again, with everything revered to the original form .

In the Christian religion, the rainbow is a symbol of God's covenant with every living man and creature. (The Bible, Book of Genesis, Chapter 9. )

The old weather lore in England is if you see a rainbow in the morning it is a very reliable forecast for more rain that day. Conversely, if you see a rainbow in the evening, again it is a very reliable forecast of no more rain that day.

So there you have it , about rainbows appearing in the sky!!!!!

Can people track down where the Rainbow ends?

User Avatar

Asked by Wiki User

No, the end of a rainbow is not a physical location that can be tracked down. Rainbows are optical phenomena caused by the reflection, refraction, and dispersion of light in water droplets. They appear to end in a certain area, but as you move closer, the rainbow will shift or disappear altogether.

Why do snails appear after rain?

User Avatar

Asked by Wiki User

Because, they like to come out in the rain.

I don't think so! Snails, grubs, and earthworms come out of the ground after a rain,

even though they know that in doing so they're exposing themselves to their natural

enemies such as birds, for whom they constitute a large and tasty dinner, because

they can't breathe in saturated ground, and they have to come out to avoid drowning !

How did they get the phrase taste the rainbow.?

By eating skittles apparently.

Where do unicorns live?

User Avatar

Asked by Wiki User

Unless you didn't receive the memo. Unicorns are still a myth or a legend. None have ever been seen, no fossils have been found and they only appear in drawings and literature dating back to 5th century BC. Just like dragons, they are easily talked about and to describe but hard to prove.

Does target have rainbow looms?

User Avatar

Asked by Wiki User

Target stores do not carry the official Rainbow Loom, which is available at Amazon online and on the Rainbow Loom website (link below,) as well as at Michael's Crafts and the Learning Express toy stores. Target carries the Cra-Z-Loom, which is a similar rubber band loom toy. The biggest difference is that the Cra-Z-Loom cannot be changed into various configurations as can the Rainbow Loom.

What do you get when you mix white with a colour?

User Avatar

Asked by Wiki User

Depending on the amount of each colour you mix, you will create a shade of pink. It is best to add the red to the white, then the black as it is easier to darken a lighter colour than it is to brighten a dark colour. Add small amounts until you reach the desired shade or tint.
