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.)

The answer is Rayleigh scattering. Shorter wavelengths are more readily absorbed by dust particles (and other obstacles) than longer wavelengths. This is also why you need only one subwoofer but many tweeters in an audio system. The higher frequencies are muffled when there are obstacles in its path, such as furniture.

Among visible colors, red has the shortest wavelength and violet has the longest. The airborne dust particles tend to block the red end of the spectrum while the violet end is transmitted more easily.

Think of it this way. Suppose there is a travelling wave approaching a particle. When the particle is small enough, and the wavelength is long enough, the wave can simply bypass the particle, and there is no loss of power. Conversely, if the particle is large relative to the wavelength, the wave will not be able to bypass the particle as easily.

THE sky is blue bcoz of the dispersion of blue light from the visible spectrum of light

the first thing to recognise is that the sun is an extremely bright source of light

and the second thing is that the oxygen n nitrogen atoms in the atmosphere have some effect on the sunlight

there's a physical phenomenon called
RAYLEIGH SCATTERING
that causes when light passes thru particles of diameter less than one tenth of the wavelength of light

thus the elements present in the sky reflect the blue light towards u more effectively than the lights of other colors are


SO the SKY appears to be BLUE

ma`am the reason for the sky being blue is that blue is the longest wave in the visual spectrum of light, now the oxygen and nitrogen in the atmosphere diffuse the all the light waves but since blue is the longest it gets diffused up to 20 time more often making it more presentable among the other colors but i suggest putting a little more simply when explaining it to your daughter : )

Light coming from the sun is what's called "white light" White light contains all the colors of the rainbow. When it enters Earth's atmosphere this light is separated into its individual colors by chemical elements in the atmosphere and scattered across the sky. Nitrogen is the most abundant element in our atmosphere, and that element scatters the color blue across our sky more than the other colors. In space, there is no atmosphere to separate colors from the white light and space looks black.

Since the color of the sky is largely determining on how the suns rays interact with water vapor, it could effect the color of the sky in blue.

When cloudy it is not blue.

But it is blue if there are no clouds.

To understand this you need to understand how we see the colours.

A blue colour body eats up all the other colours and reflects only blue colour back so we see blue. Same with every other colour.

Clear sky is clear, but blue colour light is more penetrating so it is the only light we are able to see all others are not able to reach wide deep Sky or blue yonder as it is known as, poetically.

the sky appears blue due to scattering of light with particles in air. Not even sky but also sea or ocean appears blue due to the scattering of light with water.

ha ha ha good question..she must ask like that..

k..let me answer..that is the apperance of blue color is in stratospere..in that water particles is presence in the air.

when sunlight is comes through that..because of the raman effect of white light defraction it spreads in to seven colours.

the red colour is having the highest wavelenth so it reaches our earth.but the blue colour spreads and appears as a layer,
thats y the sky apperas to be blue in color..

the molecules in the air scatter blue light more than red light from the sun...however you can always tell her some made up answer until she gets old enough to understand..like because green was already taken by the grass..ect
