any good suugestions as to why there are 7 colors in the rainbow?

Answer 1

http://eo.ucar.edu/rainbows/

The traditional description of the rainbow is that it is made up of seven colors - red, orange, yellow, green, blue, indigo, and violet. Actually, the rainbow is a whole continuum of colors from red to violet and even beyond the colors that the eye can see.

Sunlight is made up of the whole range of colors that the eye can detect. The range of sunlight colors, when combined, looks white to the eye. This property of sunlight was first demonstrated by Sir Isaac Newton in 1666.
Light of different colors is refracted by different amounts when it passes from one medium (air, for example) into another (water or glass, for example

Answer 2

A science nerd would yammer about the spetrum of colors, and the wave lengths the human eye can detect, but i think of it differently. what number would you prefer, 6? but where would that leave indigo? it is the most distinct color transition in the rainbow, and can't be left out. or maybe a different number would ticke your fancy? 3, perhaps? you expect nature to skip over all the others and show you just red, yellow, and blue? There are seven colors in the rainbow. you don't need to know why for it to be true. So just deal with it!

Answer 3

What makes the colors in the rainbow?
The traditional description of the rainbow is that it is made up of seven colors - red, orange, yellow, green, blue, indigo, and violet. Actually, the rainbow is a whole continuum of colors from red to violet and even beyond the colors that the eye can see.
The colors of the rainbow arise from two basic facts:

Sunlight is made up of the whole range of colors that the eye can detect. The range of sunlight colors, when combined, looks white to the eye. This property of sunlight was first demonstrated by Sir Isaac Newton in 1666.
Light of different colors is refracted by different amounts when it passes from one medium (air, for example) into another (water or glass, for example).

Answer 4

Guess you could argue that there are technically six....

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. Even though a rainbow spans a continuous spectrum of colours, traditionally the full sequence of colours is most commonly cited as red, orange, yellow, green, blue, and violet. It is commonly thought that indigo was included due to the different religious connotations of the numbers six and seven at the time of Isaac Newton's work on light, despite its lack of scientific significance and the poor ability of humans to distinguish colours in the blue portion of the visual spectrum.

Answer 5

There are actually significantly more than seven, however the 7 you see are the most visible colours of the spectrum. When light passes through the droplets of water suspended in the air they act light a prism, splitting the white light from the sun into the full spectrum of light. These colours are easily remembered as ROYGBIV (Red, Orange, Yellow, Green, Blue, Indigo, Violet)

Answer 6

This is caused by a persons eyes humans have poor seeing.Ultra Violet and Infrared light give you 7 different colors:
Red
orange
yellow
green
blue
indigo
violet
All these colors are made by the human eye.Or the suns direct light on the Earth by radiation there are different kinds:Visible light,Infrared,and Ultra Violet in between is the rainbow.A.K.A:Visible light are the only colors we see often.

Answer 7

in the bible, 7 is the number of completion and the rainbow was a sign of the promise at the end of the flood. the 7 colors show that the promise was complete

Answer 8

There are a lot more colors that seven. Seven distinct separate colors was the easiest way of defining the spectrum so it became the norm to say seven--listing all of them would be redundant. SJ girl has the best answer.

Answer 9

Because of the following poem..

2 little clouds one summers day
went flying through the sky
they went so fast they bumped their heads
and both began to cry

Old father sun looked down and said
Oh, never mind my dears
i'll send my little fary folks
to dry your falling tears

One fary came in VIOLET
and one wore INDIGO
In BLUE, GREEN, YELLOW, ORANGE, RED
they made a pretty bow

And thats why there are only seven colors

Answer 10

because the white sunlight is the mix of the 7 spectral colours, the raindrops break the light into the spectrum and so create the rainbow.
