why is the grass green and the sky blue and a rose red???

Answer 1

The grass is green because of chlorophyll in their pigments. The sky is blue. The blue colored sky is the result of the air scattering sunlight. The rose is red because it absorbs all colors except red which it reflects back at you.

Answer 2

The sky is blue in part because air scatters short-wavelength ordinary in decision to longer wavelengths. the position the picture voltaic is almost tangent to the Earth's floor, the ordinary's route through the ambience is see you later that most of the blue or maybe yellow ordinary is scattered out, leaving the solar rays and the clouds it illuminates red, at damage of day and sundown. Scattering and absorption are significant causes of the attenuation of radiation by technique of the ambience. Scattering varies as a function of the ratio of the particle diameter to the wavelength of the radiation. even as this ratio is below about one-10th, Rayleigh scattering takes position in which the scattering coefficient varies inversely because the fourth ability of the wavelength. At more suitable values of the ratio of particle diameter to wavelength, the scattering varies in a complicated trend defined, for round debris, by technique of the Mie concept; at a ratio of the order of 10, the guidelines of geometric optics start up to coach. human being gas molecules are too small to scatter ordinary effectively. besides the undeniable fact that, in a gas, the molecules flow more suitable or a lot less independently of each-different, unlike in beverages and solids the position the density is determined the molecule's sizes. So the densities of gases, alongside with organic air, are concern to statistical fluctuations. significant fluctuations are a lot more suitable common on a small scale. it truly is specially those density fluctuations on a small (tens of nanometers) scale that reason the sky to be blue.

Answer 3

Grass appears green because all of the colors in the rainbow are absorbed into the leaves of the grass except green.
A rose may appear red because all of the colors in the rainbow are absorbed into the petals except red.
and on and on and on

Answer 4

Rose is not always red, you have a varity of colours of roses white, pink, black etc... Even the sky is not always blue, during sunrise and sunset it takes up a orangish hue, at night it is pich black . and grass too turn yellow and brown.

Answer 5

grass is green becoz of presence of chroloplasts and rose is red becoz of the presence of chromoplasts

Answer 6

All miracle of God. Sab bhagwan ki maya hai. I have rose of many colours. You can change colours on paper.

Answer 7

Natures way of making a kaleidoscope.

Answer 8

due to the colour and vision of eye

Answer 9

Oh!!!!! simple due to reflectoin of light

Answer 10

Because they just are.
