why is the sky blue and the grass green?

Answer 1

some grass is green because of chlorophyl (spelling...) its a substance that causes it to be green (same with trees) however lacking that can cause it to be brown instead

as for the blue sky, space is black and you can see that at night because the suns rays are not passing through the atmospeare above us but during the day the light is passing through our atmosphere and it lightens the sky from our point of view, at least thats how iv always thought of it.

Answer 2

Grass is green because of a pigment called Chlorophyll. A pigment is a type of stuff that absorbs particular colours bit reflects others. So Chlorophyll sucks all the colours except for green into it, and lets green bounce back into our eyes.

Chlorophyll works with other tiny cells to help the plant absorb light from the sun, which, with some other substances, turns sunlight into sugar, which helps the plant grow. It's called Photosynthesis.

The sky is blue because of a natural phenonemon called Diffuse Sky Radiation.

If you have ever had a crystal that hangs in the sunlight and puts out little rainbows everywhere, you will find it easier to understand the next bit.

When the light from the sun shines through the atmosphere, all the millions of atoms and molecules that make up the air in the atmosphere act as trillions of tiny little crystals. The sun shines into them and scatters almost all the colours except for blue (because blue is a higher wavelength).

Because all the other colours are scattered away, blue is the only colour that can shine through the atmosphere and reach our eyes. So that's why the sky is blue!

I know this answer is similar to the ones above but I thought you might like my suggestion in case it's easier to understand or something :)

Answer 3

Grass absorbs all light but reflects green
The sky is slightly different.

A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colours because the blue light has been scattered out and away from the line of sight.

The molecules of oxygen and nitrogen in the air are sufficient to account for the scattering effect.

The white light from the sun is a mixture of all colours of the rainbow. This was demonstrated by Isaac Newton, who used a prism to separate the different colours and so form a spectrum. The colours of light are distinguished by their different wavelengths. The visible part of the spectrum ranges from red light with a wavelength of about 720 nm, to violet with a wavelength of about 380 nm, with orange, yellow, green, blue and indigo between. The three different types of colour receptors in the retina of the human eye respond most strongly to red, green and blue wavelengths, giving us our colour vision.

Answer 4

short solutions: Grass is eco-friendly through chlorophyll, the sky is blue through scattering of light by air debris. lengthy answer: colors is how we go with the mild of distinct wavelength. the coloration of issues relies upon on which wavelengths of light they take up and which wavelengths they reflect. Chlorophyll absorbs quite often blue and pink factors of light spectrum, so we see the fairway mild that it reflects. it truly is why grass and tree leaves are eco-friendly. debris in the ambience are very very small, they are smaller than the wavelength of the blue portion of light spectrum, yet are larger than the wavelength of the pink section. so that they take up the pink coloration and scatter/reflect the blue coloration. it truly is why the sky on a sunny day looks blue.

Answer 5

Maybe through light refraction................. the thing that allows us to See the wonderful rainbow spectrum , Is it the same as the blue or grey sea depending on the the sky?

Answer 6

Short answer: Atmosphere and chlorophyll

Answer 7

Light refraction.
That same thing that makes the rainbow.

Answer 8

night and day

Answer 9

becausse God made it that way
