why did rainbows exists?

Answer 1

Good question. When this happens, when you see a rainbow, you are standing between the Sun and the rainbow, with rain between you and the rainbow. The sunlight comes from behind your back and is reflected from the drops of rain in the direction of the rainbow and back to your eyes. The rain drops separates or refracts the white light of the Sun into its separate colors violet through orange and red. Check this out the next time you see a rainbow. Look to see where you are, where the sun is, and where the rainbow is. Ok? And yes, God set the rainbow in the sky as a sign that He would never flood the earth again.

Answer 2

A rainbow is an optical and meteorological phenomenon that causes a nearly continuous spectrum of light to appear in the sky when the Sun shines onto droplets of moisture in the Earth's atmosphere. It takes the form of a multicoloured arc, with red on the outside and violet on the inside. More rarely, a double rainbow is seen, which includes a second, fainter arc with colours in the opposite order, that is, with violet on the outside and red on the inside.

Even though a rainbow spans a continuous spectrum of colours, traditionally the full sequence of colours is most commonly cited and remembered as red, orange, yellow, green, blue, indigo and violet

Answer 3

Actually, a rainbow is a Circle of light; we only see the curved half. Read on: Rainbows are light. You can't touch them. You can't reach around behind them. They exist only in the eyes and sometimes the photographs of the people who see them.
Light, or more specifically visible light, includes every color we can see, with violets and blues on one end of the spectrum and oranges and reds at the other end. A rainbow is visible light broken into what we see as seven colors: red, orange, yellow, green, blue, indigo and violet.

Answer 4

The fundamental process at work in a rainbow is refraction -- the "bending" of light. Drops of rainwater can refract and disperse light in the same basic way as a prism. In the right conditions, this refraction forms rainbows.

Answer 5

They exist because God put a rainbow in existence to show the world that He promises to not flood the earth again.

Answer 6

When you put a light beam into a crystal, it is divided into the primary colors... red, purple yellow and so, the colors in the rainbow.... so, when you see a rainbow it is exactly the same, you have the sun, then you have an area where it's raining or there is fog... and rain drops or those drops in fog work as crystals, and they break light into its primary colors... that's what we see.

Answer 7

First, God put it to remind Him of his promise not to punish the earth with flood.

Next, it is a result of the refraction of light (from the sun). this is how it happens.
water droplets which hang in the air after the rain refract the rays of the sun that pass through them, this is exactly what a prism will do. now, how do the colours form? the rays of the sun don't all fo in one direction so different rays hit different droplets at different angles. and the fact that they are hit at different angles produce different colours, hence, the red, orange, yellow, green, blue, indigo and violet (ROYGBIV).

Answer 8

Thats why rain falls while the sun is out

Answer 9

The scientific answers are all good.

The spiritual answer is GOD put the bow in the sky to show his love
of mankind.

Answer 10

you mean why do they?

it's the refraction of light.
