why does the sky look blue?

Answer 1

because air is comprised mostly of Nitrogen, which has a blueish cast.

Answer 2

Most of you people where should look up the stuff b4 you state something....COMMON MISCONCEPTION: THE SKY IS NOT REFLECTING THE OCEAN

The blue is caused by the wave inteference of white light and Nitrogen...When the light in the atmosphere is broken down into the spectrum, the nitrogen absorbs or reflects all the colors. WHen this happens, electrons are pushed to the outer shell...as the electrons move back, and the energy levels fall, the released energy is is convertered into blue visible light (einstien's theory E=mc^2). This is the real reason why the sky is blue.

And for you people thinking that its a reflection, think logically, how can the sky be blue when you are land-locked??? There aren't giant mirrors reflecting the reflected blue light into the atmosphere.

Answer 3

Here is something interesting to think about: When you look at the sky at night, it is black, with the stars and the moon forming points of light on that black background. So why is it that, during the day, the sky does not remain black with the sun acting as another point of light? Why does the daytime sky turn a bright blue and the stars disappear?

The first thing to recognize is that the sun is an extremely bright source of light -- much brighter than the moon. The second thing to recognize is that the atoms of nitrogen and oxygen in the atmosphere have an effect on the sunlight that passes through them.

There is a physical phenomenon called Rayleigh scattering that causes light to scatter when it passes through particles that have a diameter one-tenth that of the wavelength (color) of the light. Sunlight is made up of all different colors of light, but because of the elements in the atmosphere the color blue is scattered much more efficiently than the other colors.

So when you look at the sky on a clear day, you can see the sun as a bright disk. The blueness you see everywhere else is all of the atoms in the atmosphere scattering blue light toward you. (Because red light, yellow light, green light and the other colors aren't scattered nearly as well, you see the sky as blue.)

Answer 4

The ocean is actually a reflection of the skys blue. Water is clear, unless poluted, dyed, or colored

by the way, grass is green cuz it has chlorophyll, the stuff that stains your clothes green when you trip onto a patch of grass.

and to answer the original question, the light travelling thru the atmosphere is altered with every layer, and the final result is a light blue shade

Answer 5

It has nothing to do with the ocean. Light moving through the molecules in our atmosphere filter out most of the other colors except blue. The ocean appears blue because it is refecting the color of the sky. The ocean is not blue on a cloudy day is it?

Answer 6

he blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through. Little of the red, orange and yellow light is affected by the air.

However, much of the shorter wavelength light is absorbed by the gas molecules. The absorbed blue light is then radiated in different directions. It gets scattered all around the sky. Whichever direction you look, some of this scattered blue light reaches you. Since you see the blue light from everywhere overhead, the sky looks blue.

Answer 7

Aqui tengo una respuesta en español para Australia
Debido al nitrogeno contenido en el aire.Porque con la cantidad de aire lo que se nota es el color azul.


Saludos a todos los Australianos.
Gracias por existir ustedes tambien yo.
La abuela Her Surname was ( Bate) de mama era de Australia y se vino a Paraguay como colono.Saludos desde Paraguay. Soy Erlis Gonzalez mi e-mail es [e-mail] escribanme igual en ingles yo les respondere en ingles tambien(Please sendme e-mails is the same for me that you send yours mails in english I will anwser in English too!!!!
Thank you .!!!

Answer 8

Think its sumfin 2 do with the sun reflecting off the sea n thts why its dark at night, cos theres not much light.

Answer 9

It is a reflection from the oceans on the atmosphere

Answer 10

If you thinks so ,especially if ones in blue mood's
