Question

why does sky appears blur give reasons

Answer 1

Sky appears Blue in colour because of the scattering and dispersion of light by the atmospheric molecules. The light gets incident on these particles , the sunlight get scattered. As the blue colur has the lowest wavelength it gets scattered a lot and red colour having the highest wavelenght the lowest. So Due to large scattering of Blue colour the most it appears in the sky and make it look of blue colour.

Answer 2

The sky looks blue because red, orange and yellow (long wavelength light ) are absorbed more strongly by the sky than is blue(short wavelength light). So when white light from the sun enters the sky , it is mostly the that get returns...that is why sky is blue
