Question

why is the sky blue! explain.

Answer 1

The blue of the sky is the result of the diffusion of sunlight through the atmosphere. If it did not exist, one would see a celestial vault all black and the stars would be visible in broad daylight.

The white light of the Sun is a mixture of all the colors of the rainbow. The light travels in the form of waves of different lengths. Each color has its own wavelength. The light travels in a straight line until it encounters an obstacle that returns it in another direction. When the sun's rays enter the atmosphere, they encounter atoms, air molecules, drops of water and the dust from which the atmosphere is formed. The air molecules have the right size to diffuse the shortest wavelengths of light, purple, indigo and blue in this case; The longer wavelengths, such as the red ones, are scarcely diffused by these air molecules.


It is therefore a mixture of violet, indigo, blue, green and a small fraction of the other colors that are diffused throughout the sky, conferring this blue which is well known.

Answer 2

the blue color of the sky

----------------------------------------------------------------------------------------

The color of the sky is due to the property of dispersion of light the white light of the color before reaching the earth's surface gets dispersed into its 7 components VIBGYOR the molecules present in the atmosphere are capable of scattering only the light with the shortest wavelength and hence red light won't get scattered

As the light that we get from sun is white in color and due to atmospheric refraction splitting up of white light takes place and the light with the longest wavelength gets lost in the space and blue and violet has the shortest wavelength but the intensity of blue will be much more than that of violet which makes us see the sky blue in color and our eyes are more sensitive to blue light
