Question

Why the sky is blue in colour

Answer 1

$\huge\mathfrak\red{Answer :}$


The sky is blue because molecules present in air scatters the blue light most from the sun than that of red light... 

Due to this scattering of blue light by air molecules... a blue colour enters into our eyes and we saw the sky; blue in colour...

But during sunset we saw the sky in reddish colour because at that time blue light has been scattered out and red - orange colour reach to our eyes...

Hence, during sunset we saw the sky in reddish colour...

Answer 2

Answer:

the blue color of sky

Explanation:

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
