Question

Why the colour of sky is Blue.

Answer 1

Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors because it travels as shorter,smaller waves.That's why we see a blue sky most of the time.Hope it helps

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
